Answer: ? = 1/2
Explanation:
Your question is a bad example, so let me come up with one.
2/8 = 1/4
This is done by dividing both the numerator and denominator by the same value: 2/8 / 2/2
or
2/2 = 1, 8/2 = 4
We now have 1/4
or 9/36
What can we divide 36 by, 9 by? We need to divide by both for it to work.
9/3 = 3
36/3 = 12
3/12 But we can divide this again
3/3 = 1
12/3 = 4
1/4, we could also have divided 9/36 by 6/6 to get 1/4
For 1/8 to get ?/4, we do
8/? = 4
? = 1/2
, so the answer is 1/2/4 = 1/2*4 = 1/8
