D) 3/2 : 12

Answer 1

Resposta:

A) 4/5 ÷ 2/3 = 6/5.

B) 1/4 ÷ 7/3 = 3/28.

C) 1/10 ÷ 1/10 = 1.

D) 3/2 ÷ 12 = 1/8.

Explicação passo a passo:

TEORIA DA DIVISÃO ENTRE FRAÇÕES:

X/Y ÷ P/Q = X/Y × Q/P

A) 4/5 ÷ 2/3 =

= 4/5 × 3/2 =

= (4 × 3)/(5 × 2) =

= 12/10 =

= 6/5

B) 1/4 ÷ 7/3 =

= 1/4 × 3/7 =

= (1 × 3)/(4 × 7) =

= 3/28

C) 1/10 ÷ 1/10 =

= 1/10 × 10/1 =

= (1 × 10)/(10 × 1) =

= 10/10 =

= 1

D) 3/2 ÷ 12 =

= 3/2 × 1/12 =

= (3 × 1)/(2 × 12) =

= 3/24 =

= 1/8
