a) 2/5 de R$80,00
b) 2/9 de R$1800,00​

Answer 1

Resposta:

5)

a)

$\frac{2}{5} \times \frac{80}{1} = \\ \\ = \frac{2 \times 80}{5 \times 1} \\ \\ = \frac{160}{5} \\ \\ = \Large \boxed{ \green{ \bf32,00 \: reais}}$

b)

$\frac{2}{9} \times \frac{1800}{1} = \\ \\ = \frac{2 \times 1800}{9 \times 1} \\ \\ = \frac{3600}{9} \\ \\ = \Large \boxed{ \green{ \bf 400,00 \:reais}} \\ \\ \Large \boxed{ \underline{ \blue{ \bf \: Bons \: Estudos! } \: \bf \: 21/05/2021}}$
