Question

a) 40

b) - 40

c) 0

d) - 10

​

Answer 1

x = [(-8/5) ÷ (-16/100)] ÷ 0,25 + 50/17 ÷ (-5/68).

- com - = +.

[8/5 × 100/16] = [1/1 × 20/2] = 20/2 = 10.

10 ÷ 25/100 + 50/17 ÷ (-5/68).

10/1 × 100/25 + 50/17 × (-68/5).

2/1 × 100/5 + 10/1 × (-4/1).

200/5 + (-40) = 40 + (-40) = 0.

x = 0.

0 ÷ 500 = 0.
