ME AJUDA POR FAVOR ​

Answer 1

Olá!

A) $\frac{1}{4} + \frac{1}{4} = \frac{1 + 1}{4} = \frac{2}{4}$

B) $\frac{3}{35} + \frac{2}{25} = \frac{15 + 14}{175} = \frac{29}{175}$

C) $\frac{3}{10} + \frac{1}{10} = \frac{3 + 1}{10} = \frac{4}{10}$

D) $\frac{4}{5} - \frac{2}{5} = \frac{4 - 2}{5} = \frac{2}{5}$

E) $\frac{2}{10} \times \frac{7}{5} = \frac{1}{5} \times \frac{7}{5} = \frac{7}{25}$

F) $\frac{5}{15} \times \frac{2}{6} = \frac{1}{3} \times \frac{2}{6} = \frac{1}{3} \times \frac{1}{3} = \frac{1}{9}$

Espero ter ajudado, bons estudos! =)
