Answer 1

Resposta:

1

$\frac{11}{10}$

2

$\frac{1}{6}$

Explicação passo-a-passo:

$\frac{2}{4} + \frac{3}{5} \\ \frac{1}{2} + \frac{3}{5} = \frac{1 \times 5}{2 \times 5} + \frac{3}{5} \\ \frac{1 \times 5}{2 \times 5} + \frac{3 \times 2}{5 \times 2} \\ \frac{5}{2 \times 5} + \frac{3 \times 2}{5 \times 2} = \frac{5}{10} + \frac{3 \times 2}{5 \times 2} = \frac{5}{10} + \frac{6}{5 \times 2} = \frac{5}{10} + \frac{6}{10} \\ \frac{5 + 6}{10} = \frac{11}{10}$

$\frac{6}{12} - \frac{4}{12} \\ \frac{6 - 4}{12} = \frac{2}{12} \\ \frac{1}{6}$
