a) 1 + 3/4
b) 1 - 3/4
c) 5/8 x 5/6
d) 4/5 ÷ 3/8
e) (2/3)⁵ x (1/2)⁶​

Answer 1

Resposta:

a) 1,75

b) 0,25

c) 25/48

d) 32/15

e) 1/486

Explicação passo a passo:

a) 1 + 3/4

(3/4 = 0,75)

1 + 0,75 =

1,75.

b) 1 - 3/4

(3/4 = 0,75)

1 - 0,75 =

0,25.

c) 5/8 × 5/6

5/8 × 5/6 =

(5×5)/(8×6) =

25/48.

d) 4/5 ÷ 3/8

4/5 ÷ 3/8 =

4/5 × 8/3 =

(4×8)/(5×3) =

32/15.

e) (2/3)⁵ × (1/2)⁶ =

(2⁵/3⁵) × (1⁶/2⁶) =

(32/243) × (1/64) =

(32×1)/(243×64) =

32/15552 =

1/486.

Espero ter ajudado :)
