Question

realize as multiplicaçoes de fração é simplifique quando possível. a) 4/5 × 1/2 b) 1/4 × 1/4 c) 1/5 × 5/8 d) 3/5 × 2/3 e) 1/2 × 1/2 f) 2/3 × 2/5

Answer 1

a) 4/5 × 1/2 = 4/10 = 2/5

b) 1/4 × 1/4 = 1/16

c) 1/5 × 5/8 = 5/40 = 1/8

d) 3/5 × 2/3 = 6/15

e) 1/2 × 1/2 = 1/4

f) 2/3 × 2/5 = 4/15

Answer 2

A) $\frac{4}{5}$ * $\frac{1}{2}$ = $\frac{4}{10}$ = $\frac{2}{5}$

B)  $\frac{1}{4}$ * $\frac{1}{4}$ = $\frac{1}{16}$

C) $\frac{1}{5}$ * $\frac{5}{8}$ = $\frac{5}{40}$ = $\frac{1}{8}$

D)  $\frac{3}{5}$ * $\frac{2}{3}$= $\frac{6}{15}$= $\frac{2}{5}$

E) $\frac{1}{2}$ *$\frac{1}{2}$ = $\frac{1}{4}$

F) $\frac{2}{3}$ *$\frac{2}{5}$ = $\frac{4}{15}$
