Question

How many times does 51 go into 470

Answer 1

It goes in 9 times that’s the answer

Answer 2

You can do some rounding and reach that 450 goes into 50 9 times, so this won't be that far. So, 51 * 9 is equal to 459, and there is a remainder of 11. So, you can put it in mixed fraction form as:
$9 \frac{11}{51}$

And that's your answer!
