Question

What number cannot be divided into 9 groups without a remainder?

Answer 1

The answer is B) 432

Explanation:

The 4 in 432 becomes a 3, because we can't subtract 6 from 3. The 3 becomes 13 and if we subtract 13 with 6... We get 7.

I got 0 with option B... With A I got 2 which is a remainder. With C I got 6.5 (repeating). And with D I got 7.77777777778.

Hence, B) 432 is the correct option.

(I forgot to include 48 on top of the division I just did. Don't mind that too much..)

Answer 2

A) 326

`(326)/(9)`

`= 36.2222222222`

B) 432

`(432)/(9)`

`= 48`

C) 531

`(531)/(9)`

`= 59`

D) 630

`(630)/(9)`

`= 70`

so, the correct answer is option A.
