How do you know if 75 goes in to 9 8 times?

Answer 1

Easily; it doesn't as 75 is greater than 9, 75 cannot go into 9 any times.

However, if you mean if 9 goes into 75, then:

you can repeatedly subtract 9 from 75 until the result is less than 9 and greater than or equal to 0, and count how many times you could subtract 9:

1. 75 - 9 = 66
2. 66 - 9 = 57
3. 57 - 9 = 48
4. 48 - 9 = 39
5. 39 - 9 = 30
6. 30 - 9 = 21
7. 21 - 9 = 12
8. 12 - 9 = 3

So 9 could be subtracted 8 times from 75 until it could be subtracted no more without the result going negative,

Thus 9 goes into 75 8 times (with a remainder of 3), ie 75 ÷ 9 = 8 r 3

Alternatively, knowing your 9 times table, you would know that 9 × 8 = 72, and as 75 - 72 = 3 < 9 then 75 ÷ 9 = 8 r 3.
