Question

3/5 + 8/7
5/10 - 4/10
4/8 x 10/7
7/5 ÷ 8/9​

Answer 1

Explicación paso a paso:

$\frac{3}{5} + \frac{8}{7} = \frac{21 + 40}{35} = \frac{61}{35}$

$\frac{5}{10} - \frac{4}{10} = \frac{50 - 40}{100} = \frac{10}{100 } = \frac{1}{10}$

$\frac{4}{8} \times \frac{10}{7} = \frac{4 \times 10}{8 \times 7} = \frac{40}{56} = \frac{5}{7}$

$\frac{7}{5} \div \frac{8}{9} = \frac{7 \times 9}{8 \times 5} = \frac{63}{40}$
