Question

$\frac{2}{3} \div(0.4 + 0.4 \div 3) \\ 50 \div (0.1 - \frac{1}{10} \div 5) \\ (8 - \frac{8}{3} \times 1.5) \times 2$

Answer 1

2/3 : (0,4 + 0,4 : 3) =

= 2/3 : (4/10 + 4/10 x 1/3)

= 2/3 : (12/30 + 4/30)

= 2/3 x 30/16

= 10/8

= 5/4

50 : (0,1 - 1/10 : 5)

= 50 : (1/10 - 1/10x1/5)

= 50 : (5/10 - 1/50)

= 50 x 4/50

= 4

(8 - 8/3 x 1,5) x 2

= (8 - 8/2)x2

= 8 - 4)x2

= 4x2

= 8
