Question

Me ajudem

A) [(18+3•2):8+5:3]:6 =
B) 60:{2•[-7+18:(3+12) =

Answer 1

Explicação passo-a-passo:

A=

$((18 + 3.2) \div 8 + 5 \div 3) \div 6$

$(21.2 \div 8 + \frac{5}{3} ) \times \frac{1}{6}$

$(2.65 + \frac{5}{3} ) \times \frac{1}{6}$

$( \frac{53}{20} + \frac{5}{3}) \times \frac{1}{6}$

$\frac{259}{60} \times \frac{1}{6}$

Solução

$\frac{259}{360}$

B=

$60 \div (2( - 7 + 18 \div (3 + 12)))$

$60 \div (2( - 7 + 18 \div 15))$

$60 \div (2( - 7 + 1.2))$

$60 \div (2 \times ( - 5.8))$

$60 \div ( - 11.6)$

$60 \div ( - \frac{58}{5} )$

$- 60 \times \frac{5}{58}$

$- 30 \times \frac{5}{29}$

Solução

$\frac{150}{29}$
