To write 9 as 63, you need to multiply it by a number. 63/9 = 7.
So you need to multiply 9 by 7 to get 63.
But since it's a fraction, you can't multiply the denominator without multiply the numerator. So you need to multiply the denominator, 9, by 7 and the numerator, 8, by 7.
8/9 = (8*7) / (9*7) = 56/63
So 8/9 = 56/63
Hope this helps! :)
