resolver com contas

a) 20 x [(15 – 60 ÷ 10) ÷ 3] =

b) 200 – [3 x (25 – 12) + 9] =

c) [25 x (25 ÷ 5 – 1)] ÷ 10 =

d) 1410 ÷ [(225 + 120 ÷ 12) x 2] =

Answer 1

Resposta:

a = 60

b = 152

c = 10

d = 3

Explicação passo-a-passo:

a) 20 x [(15 – 60 ÷ 10) ÷ 3]

20 x [(15-6) ÷ 3]

20 x [9 ÷ 3]

20 x 3

= 60

b) 200 – [3 x (25 – 12) + 9]

200 - [3 x 13 + 9]

200-48

= 152

c) [25 x (25 ÷ 5 – 1)] ÷ 10

[25 x (5 - 1)] ÷ 10

[25 x 4] ÷ 10

100 ÷ 10

= 10

d) 1410 ÷ [(225 + 120 ÷ 12) x 2]

1410 ÷ [(225 + 10) x 2]

1410 ÷ [235 x 2]

1410 ÷ 470

= 3
