Question

Para as frações irredutíveis abaixo, determine as porcentagens correspondentes a)1/5 b)4/5 c)9/20 d)5/8 e)3/5 f)2/4


Rápido pfvrrr

Answer 1

a)1 ÷ 5 = 0.2

0.2 × 100 = 20%

b)4 ÷ 5 = 0.8

0.8 × 100 = 80%

c)9 ÷ 20 = 0.45

0.45 × 100 = 45%

d)5 ÷ 8 = 0.625

0.625 × 100 = 62.5%

e)3 ÷ 5 = 0.6

0.6 × 100 = 60%

f)2 ÷ 4 = 0.5

0.5 × 100 = 50%
