3.	What is sucessor of greatest 6 digit number
Answer» Answer: $\large\boxed{\sf{10,00,000}}$ Step-by-step explanation: To find the SUCCESSOR of greatest 6 DIGIT number. First of all, find the greatest 6 digit number. Now, we know that, For the greatest number, just put as many 9 as the digit of number we want. Therefore, we will GET, Greatest 6 digit number = 9,99,999 999999 = Nine lakhs ninety nine thousands nine hundred ninety nine. Now, we know that, Successor means just one more than the given number. Therefore, successor of greatest 6 digit number = 999999 + 1 = 1000000 1000000 = TEN lakhs Hence, the REQUIRED number successor of greatest 6 digit number is 10,00,000.

3.

What is sucessor of greatest 6 digit number

Answer»

Answer:

$\large\boxed{\sf{10,00,000}}$

Step-by-step explanation:

To find the SUCCESSOR of greatest 6 DIGIT number.

First of all, find the greatest 6 digit number.

Now, we know that,

For the greatest number, just put as many 9 as the digit of number we want.

Therefore, we will GET,

Greatest 6 digit number = 9,99,999

999999 = Nine lakhs ninety nine thousands nine hundred ninety nine.

Now, we know that,

Successor means just one more than the given number.

Therefore, successor of greatest 6 digit number

= 999999 + 1

= 1000000

1000000 = TEN lakhs

Hence, the REQUIRED number successor of greatest 6 digit number is 10,00,000.

38.	1. Check whether rational numbers are associative with thefour operations
Answer» Step-by-step explanation: Addition of rational NUMBERS with same denominators: CONSIDER two rational numbers 2/9 and 3/9, here both have different numerators but same denominators. To add these, we add both the numerators keeping common denominator. Addition of rational numbers with different denominators: To add rational numbers with different denominators convert them to rational numbers with same denominators and then add. In order to convert rational numbers to numbers with same denominators take the LCM of the denominators. Then multiply both rational numbers by this LCM and we will get equivalent rational numbers with this LCM as the denominator. Additive Inverse Opposite of a number is the number with same MAGNITUDE of opposite sign. -1 is the opposite of 1. The sum of a number and its opposite is always zero. This is same for rational numbers also. Two rational numbers are additive inverse of each other when their sum is zero. Thus, all opposite numbers are additive inverse to each other. Subtraction Operation on Rational Numbers Subtraction of rational numbers with same and/or different denominators can be done like addition. Subtraction of rational numbers will be easy by transforming subtraction problem into addition problem. This can be done in two steps; Change the subtraction sign (-) into addition sign (+) Take the additive inverse of the rational number come after the sign. Simply, take the additive inverse of the number after the sign and add them. Multiplication Operation on Rational number Multiplication of rational numbers is as simple as multiplication of integers. In general, product of two rational numbers will equal to the product of the numerators divided by the product of the denominators. rational number To find the product of a rational number and an integer, keep the denominator unchanged and multiply the numerators. To find the product of rational numbers, multiply the numerators and multiply denominators and write in the form given above. Division Operation on Rational Number Divisions of rational numbers are similar to the divisions of fractions. To find the quotient of rational numbers, we need to recollect the concept of reciprocal of a rational number. Reciprocal of a rational number is nothing but the SWAPPING of the numerator and denominator of that rational number i.e. invert the given the rational number will GIVE you the reciprocal of that rational number. For example, 7/6 is the reciprocal of 6/7 . The product of a number and its reciprocal will always be 1. In order to divide rational number, first change the division sign ÷ to x. Then take the reciprocal of the number after the sign and multiply. Plz mark me brainliest.

1. Check whether rational numbers are associative with thefour operations

Answer»

Step-by-step explanation:

Addition of rational NUMBERS with same denominators: CONSIDER two rational numbers 2/9 and 3/9, here both have different numerators but same denominators. To add these, we add both the numerators keeping common denominator.

Addition of rational numbers with different denominators:

To add rational numbers with different denominators convert them to rational numbers with same denominators and then add.

In order to convert rational numbers to numbers with same denominators take the LCM of the denominators. Then multiply both rational numbers by this LCM and we will get equivalent rational numbers with this LCM as the denominator.

Additive Inverse Opposite of a number is the number with same MAGNITUDE of opposite sign. -1 is the opposite of 1. The sum of a number and its opposite is always zero. This is same for rational numbers also. Two rational numbers are additive inverse of each other when their sum is zero. Thus, all opposite numbers are additive inverse to each other.

Subtraction Operation on Rational Numbers

Subtraction of rational numbers with same and/or different denominators can be done like addition. Subtraction of rational numbers will be easy by transforming subtraction problem into addition problem. This can be done in two steps;

Change the subtraction sign (-) into addition sign (+)

Take the additive inverse of the rational number come after the sign.

Simply, take the additive inverse of the number after the sign and add them.

Multiplication Operation on Rational number

Multiplication of rational numbers is as simple as multiplication of integers. In general, product of two rational numbers will equal to the product of the numerators divided by the product of the denominators.

rational number

To find the product of a rational number and an integer, keep the denominator unchanged and multiply the numerators. To find the product of rational numbers, multiply the numerators and multiply denominators and write in the form given above.

Division Operation on Rational Number

Divisions of rational numbers are similar to the divisions of fractions. To find the quotient of rational numbers, we need to recollect the concept of reciprocal of a rational number. Reciprocal of a rational number is nothing but the SWAPPING of the numerator and denominator of that rational number i.e. invert the given the rational number will GIVE you the reciprocal of that rational number. For example, 7/6 is the reciprocal of 6/7 . The product of a number and its reciprocal will always be 1.

In order to divide rational number, first change the division sign ÷ to x. Then take the reciprocal of the number after the sign and multiply.

Answer» Answer: The Rate of Interest is 2% p.a. Step-by-step EXPLANATION: Simple Interest = Rs. 750 Time = 5 yrs Principal = Rs. 7500 Rate = Simple Interest = (PRT)/100 = 750 = (7500R5)/100 = 75000 = 37500 R = 2 = Rate of Interest Hope this helps.

Find the rate of interest when principal is 7500 times is 5 years and interest is 750

Answer»

Answer:

The Rate of Interest is 2% p.a.

Step-by-step EXPLANATION:

Simple Interest = Rs. 750

Time = 5 yrs

Principal = Rs. 7500

Rate = Simple Interest = (P*R*T)/100

= 750 = (7500*R*5)/100

= 75000 = 37500 R

= 2 = Rate of Interest
