Question

What’s the way to solve

Answer 1

Answer: Half

Think of an example like comparing
`72 / 2` versus
`72`

I replaced the complicated stuff in the parenthesis with "72", and we're dealing with the same kind of problem.

Using a calculator or long division,
`72 / 2 = 36` which is half of 72.

Dividing by 2 is the same as multiplying by the fraction 1/2

`(1)/(2)*72 = 36 \ \text{ and } \ 72 / 2 = 36`

Answer 2

Twice

Explanation:

It is twice because when you get your answer of the subtraction part, you divide by 2 or 2/1 and so you got to do K.C.F.

so in the end you would be multiplying by 1/2 or 2
