Answer 1

Resposta:

0,13

Explicação passo-a-passo:

1/2x(1/5+1/2x1/3)-1/5(1/6+1/2x1/5)

1/2 . ( 1/5 + 1/6 ) - 1/5 ( 1/6 + 1/10 )

1/2 . 11/30 - 1/5 . 4/15

 11/60 - 4/75

    0,13

Answer 2

Resposta:

$\frac{1}{2} \times ( \frac{1}{5} + \frac{1}{2} \times \frac{1}{3} ) - \frac{1}{5} ( \frac{1}{6} + \frac{1}{2} \times \frac{1}{5} ) = \frac{1}{2} \times ( \frac{1}{5} + \frac{1}{6} ) - \frac{1}{5} ( \frac{1}{6} + \frac{1}{10} ) = \frac{1}{2} ( \frac{6 + 5}{30} ) - \frac{1}{5} ( \frac{5 + 3}{30}) = \frac{1}{2} ( \frac{11}{30} ) - \frac{1}{5} ( \frac{8 \div 2}{30 \div 2} ) = \frac{11}{60} - \frac{1}{5} ( \frac{4}{15} ) = \frac{11}{60} - \frac{4}{75} = \frac{55 - 16}{300} = \frac{39 \div 3}{300 \div 3} = \frac{13}{100}$
