Answer:Make the denominators the same
Explanation:
find the least common denominator
As in find there least common multiple
Then multiply both numerators and denominators to find the common multipl
Example:
2/8 multiples: 8,16,24
5/6 multiples:6,12,18,24
Least common multiple is 24
So 8*3=24
2*3=6
So 2/8=6/24
6*4= 24
5*4=20
So 5/6=20/24
Then you subtract 20/24 by 6/24
Then your done:)
