C) -3/10 +5/8 =
D) -5 +2/5 =

Answer 1

Explicação passo-a-passo:

a)

$\frac{5}{3} - \frac{4}{3} = \frac{1}{3}$

b)

$\frac{3}{8} + \frac{5}{12} = \frac{9 + 10}{24} = \frac{19}{24}$

c)

$- \frac{3}{10} + \frac{5}{8} = \frac{ - 12 + 25}{40} = \frac{13}{40}$

d)

$\frac{ - 5}{1} + \frac{2}{5} = \frac{ - 25 + 2}{5} = \frac{ - 23}{5}$
