5 Simplify 1\times 31×3 to 33.
13/4 -3 +1 / 3
6 Simplify 3+13+1 to 44.
13/4-4/3
7 (Find the Least Common Denominator (LCD) of 13/4,4/3 In other words, find the Least Common Multiple (LCM) of 4,34,3.)
LCD = 1212
8 (Make the denominators the same as the LCD)
13 x 3 - 4 x 4
4 x 3 -3 x4
9 (Simplify. Denominators are now the same.)
39/12-16/12
10 (Join the denominators.)
39-16
