Question

If the four digit number 13y1 is divisible by 9 find the smallest value of Y.

Answer 1

Answer:

If a 4 digit number i.e., 13y1 is completely divisible by 3 then,

As we know that in abcd if a + b + c + d is divisble by 3 then whole abcd ÷ 3.

In 1301,

1 + 3 + 0 + 1 is not divisible by 3

y = 0 ❎

In 1311

1 + 3 + 1 + 1 is divisible by 3

y = 1 ✔

So smallest value of y can be 1

Step-by-step explanation:

Answer 2

Answer:

1+3+y+1

5+y

THE SMALLEST MULTIPLE OF 9

Step-by-step explanation:

5+y=9
