Find four rational number between (3:5) and (2:3) |
|
Answer» As the denominators of both rational numbers are different, so first we have to make the denominators same by finding their LCM.The LCM of 5 and 3 is 15.3/5*3/3=9/152/3*5/5=10/15Now if you want you can make the numbers bigger by multiplying them.I am multiplying both the numbers with 10.9/15*10/10=90/15010/15*10/10=100/150So five rational numbers between 90/150 and 100/150 are91/150, 93/150, 95/150, 97/150 and 99/150 Nonepo |

How does π is rational and 22/7 is irrational |
|
Answer» Bhai ki fix value Nahin hai 22/7. So, is irrational ◆ As you know that π is a irrational number as it\'s decimal expension is non- terminating & Non- repeating.◆ But these statements are actually true because we have assumed the APPROPRIATE value of π as 22/7 to make calculation easier.◆ If you divide 22/7 then it\'s decimal expension will come 3.14... which as approximately value equal to π.\xa0 |

Explain Closure property |
|
Answer» For two rational numbers say x and y the results of addition, subtraction and multiplication operations give a rational number. We can say that rational numbers are closed under addition, subtraction and multiplication. For example:\t(7/6)+(2/5) = 47/30\t(5/6) – (1/3) = 1/2\t(2/5). (3/7) = 6/35 Hii |

If a + b + c = 15 and a² + b² + c² = 83, find the value of a³ + b³ + c³ – 3abc. |
| Answer» a² + b² + c² = 83 ------(1)a + b+ c = 15On squaring both sides, we geta² + b² + c² + 2( ab + bc + ca) = 225=> 83 + 2 ( ab + bc + ca) = 225=> 2 ( ab + bc + ca) = 142=> ab + bc + ca = 71 --------(2)Now,a³ + b³ + c³- 3abc = ( a +b + c) (a² + b² + c² - ab - bc - ca)= ( 15) [ 83 - (ab + bc + ca)]= (15)(83-71)= 15 × 12= 180\xa0 | |

How we can find underroots |
| Answer» To find a\xa0square root\xa0of a number\xa0without\xa0a\xa0calculator, see if you can get to that whole number by squaring smaller numbers, or multiplying a smaller number by itself. If the number is a perfect\xa0square, you will get a whole number as the\xa0square root.\xa0First, divide the number you\'re trying to\xa0find\xa0the\xa0square root\xa0of by the average. Then,\xa0find\xa0the average of that number and the original average by adding them together and dividing by 2. For example, first you would divide 7, the number you started with, by 2.16, the average you calculated, and get 3.24. | |
