Question

what least number should be added to the following numbers to make them divisible by 9? a)42724. b)39065​

Answer 1

Given,

Dividend numbers are = 42724 & 39065

Divisor is 9

For calculating the least numbers that should be added to the following numbers to make them divisible by 9,we have to divide the given numbers with 9 to get the remainders.

From mathematical calculations we get that,

The remainder for 42724÷9 is = 1

The remainder for 39065÷9 is = 5

So,the closest previous numbers which are divisible by 9 are

a) 42724-1 = 42723

b) 39065-1 = 39060

So,the next numbers which are divisible by 9 are

a) 42723+9 = 42732

b) 39060+9 = 39069

So, the least numbers we have to add are

a) 42732-42724 = 8

b) 39069-39065 = 4

Hence,the numbers that we have to add are 8 and 4 respectively.
