Answer:
each answer is written below
Step-by-step explanation
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! :)
First <span>brackets:</span>
(9 : 3) = 3(6 - 7) = (-1)
Next product
4(6 - 7) = 4(-1) = -4
Next sum
(9 : 3) + 4(6 - 7) = 3 + (-4) = -1
Answer: b) -1
