Answer 1

Resposta:

a) 3/5       b) 5/4       c) 4/7       d) 2/3

Explicação passo-a-passo:

a) 2/5 + 1/5  => $\frac{2}{5} + \frac{1}{5} => \frac{2 + 1}{5} => \frac{3}{5}$

b) 3/4+ 2/4 => $\frac{3}{4} + \frac{2}{4} => \frac{3 + 2}{4} => \frac{5}{4}$

c) 6/7- 2/7  => $\frac{6}{7} - \frac{2}{7} => \frac{6 - 2}{7} => \frac{4}{7}$

d) 4/3 – 2/3 => $\frac{4}{3} - \frac{2}{3} => \frac{4 - 2}{3} => \frac{2}{3}$
