3. First, turn the fractions into improper fractions
11/8 + 11/4
Since we can't divide 11 by 2 to make the denominator of the first fraction 2, let's multiply both sides of the second fraction by 2 instead.
11/8 + 11*2/4*2 = 11/8 + 22/8
33/8, or 4 1/8
(I already answered numbers 4 and 6 in a previous question you asked)
5. 1 1/2 + 2 3/4
Obviously, we'll start by converting the fraction into improper fractions.
3/2 + 11/4
Multiply both sides of the first fraction by 2
3*2/2*2 + 11/4 = 6/4 + 11/4 = 17/4
17/4, or 4 1/4
