Question

1/4 + 3/8 =
1 1/5 : 1 1/2 =

Answer 1

\(\dfrac{1}{4}+\dfrac{3}{8}=\dfrac{2}{8}+\dfrac{3}{8}=\dfrac{5}{8}\)

\(1\dfrac{1}{5}:1\dfrac{1}{2}=\dfrac{6}{5}:\dfrac{3}{2}=\dfrac{6}{5}\times\dfrac{2}{3}=\dfrac{4}{5}\)

Answer 2

\(\dfrac{1}{4}+\dfrac{3}{8}=\dfrac{2}{8}+\dfrac{3}{8}=\dfrac{5}{8}\)
\(1\dfrac{1}{5}:1\dfrac{1}{2}=\dfrac{6}{5}:\dfrac{3}{2}=\dfrac{6}{5}\times\dfrac{2}{3}=\dfrac{4}{5}\)

Answer 3

2/8+3/8=5/8

6/5:3/2=5/6x3/2=5/4
