You want to make the fractions have the same denominator.
2/3 = 8/12
1/4 = 3/12
now subtract the numerator and keep the denominator the same...
8/12 - 3/12 = 5/12
5 1/2 is the answer
Get common denominators, and solve for each expression
7/5 - 3/4 = 28/20 - 15/20 = 13/20
1/4 + 2/5 = 5/20 + 8/20 = 13/20
These two fractions are equivalent
