d. LCD = 30 divide numerator into 30
20/30- 18/30 =2/30 simplify divide by 2
1/15
e. multiply bottom and top
4/10×3/7 =12/70 simplify divide by 2
6/35
f.multiply bottom and top
1/6×6/15 =6/90 simplify divide by 6
1/15
g.keep the first one,change the sign, flip the second one(kcf)
1/8×9/4 =9/32
h.same thing as g.
1/5×4/3 =4/15
