Calcule a expressao numeriaca abaixo
0,018÷8,5•125/2​

Answer 1

$\frac{9}{500} \div \frac{17}{2} \times \frac{125}{2} = \frac{9}{4} \times \frac{2}{17} \times \frac{1}{2} = \frac{9}{4} \times \frac{1}{17} = \frac{9}{68}$

Answer 2

Oie, Td Bom?!

= 0,018 ÷ 8,5 . 125/2

= 9/500 ÷ 17/2 . 125/2

= 9/500 . 2/17 . 125/2

= 9/[500 ÷ 125] . 2/17 . [125 ÷ 125]/2

= 9/4 . 2/17 . 1/2

= 9/4 . [2 ÷ 2]/17 . 1/[2 ÷ 2]

= 9/4 . 1/17 . 1/1

= 9/4 . 1/17

= [9 . 1]/[4 . 17]

= 9/68
