Question

if 37y4 exactly divisible by 9 then the least value of y is_____
please answer my question someone step by step....​

Answer 1

Answer:

y=4

Step-by-step explanation:

The divisibility rule of 9 is that the sum of the digits in the number must be divisible by 9

i.e. 3+7+y+4 must be divisible by 9

so, 14+y must be divisible by 9

Let's have a look at 9's table

9×1=9

9×2=18.... and so on

therefore we see that the least possible value of y can be 4 since

14+4 is divisible by 9

i.e. 18 is divisible by 9. (9×2=18)

Hence, y = 4 is the least possible value of y for 37y4 to be exactly divisible by 9

Hope it helps!!!!!
