Answer 1

Olá!!

A) 3/7 x 2/5 = 6/35
B) 4/13 x 6/5 = 24/65
C) 4/8 x 1/4 = 4/32 = 1/8
D) 6/11 x 11/10 = 66/110 = 33/55
E) 3 x 1/2 = 3/1 x 1/2 = 3/2 = $1 \frac{1}{2}$
F) 2/5 x 5 = 2/5 x 5/1 = 10/5 = 2/1 = 2
G) 2/7 x 14/10 x 1/2 = 28/140 = 4/20 = 1/5
H) $1 \frac{4}{9}$ x 3/8 = 13/9 x 3/8 = 39/72

Espero ter ajudado!! :3
