Answer 1

Explicação passo-a-passo:

a) 1/3 + 1/5 = 8/15

b) 3/7 + 5/2 + 1/14 = 42/14 (Pode simplificar = 3/1)

c) 1/3 + 5/6 + 3/4 = 23/12

d) 7/8 - 1/6 = 17/24

e) 3/5 - 1/7 = 20/35 (Pode simplificar = 4/7)

f) 7/8 - 1/6 = 17/24

g) 1/3 × 5/6 = 5/18

h) 2/3 × 1/4 × 5/2 = 10/24 (Pode simplificar = 5/12)

i) 3/10 × 5/9 = 15/90 (Pode simplificar = 1/6)

j) 3/2 : 1/2 = 6/2 (Pode simplificar = 3/1)

k) 1/3 : 7 = 7/3

l) 5/8 : 2 = 5/16

m) (1/7)² = 1/49

n) (13/15)² = 169/225

o) (2/3)³ = 8/27
