Question

1÷2×(1÷5+1÷2×1÷3)-1÷5×(1÷6+1÷2×1÷5)=

Answer 1

Explicação passo-a-passo:

$1 \div 2 \times (1 \div 5 + 1 \div 2 \times 1 \div 3) - 1 \div 5 \times (1 \div 6 + 1 \div 2 \times 1 \div 5) \\ \\ \frac{1}{2} \times (0,2 + \frac{1}{2} \times \frac{1}{3} ) - \frac{1}{5} \times ( \frac{1}{6} + 0,1) \\ \\ \frac{1}{2} \times ( \frac{1}{5} \times \frac{1}{6} ) - \frac{1}{5} \times ( \frac{1}{6} + \frac{1}{10} ) \\ \\ \frac{1}{2} \times \frac{11}{30} - \frac{1}{5} \times \frac{4}{15} \\ \\ \frac{11}{60} - \frac{4}{75} \\ \\ \frac{13}{100} = 0,13$
