In each of the following numbers, replace* by the smallest number to make it divisible by 11 :(1.) 26*5 |
Answer» ⏩⏩⏩⏩answer⏩⏩⏩⏩⏩➡➡➡➡So first we have to KNOW the divisibility test of 11. ➡➡If the alternate numbers from right to left are ADDED as in the above number we will add 1+2+(no.we have to find=x) 3+x ➡➡And other alternate numbers as 7+3+4=14 So the rule is that when you SUBTRACT the first list of alternate numbers from the second list, the difference should be 0 or a multiple of 11. ➡➡So 3+x-14=0[As we have to find the smallest number] 3+x=14 x=14-3 x=11 ➡➡Because the number is EQUAL by 11 we will subtract 11 from the number. २1➡➡1-11=0 Therefore the smallest number is 0. |
