Efetue:
a- 1/5 + 4/5 - 5/5=
b- 1/5 - 4/5 - 5/5=
c- 1/4 - 4/5 + 5/5=

Answer 1

Olá

$\LARGE{} \frac{1}{5} + \frac{4}{5} - \frac{5}{5} \\ \\ \LARGE{} \frac{1 + 4 -5 }{5} \\ \\ \\ \LARGE{} \frac{0}{5} \\ \\ \LARGE\boxed{0}$

B)

$\LARGE{} \frac{1}{5} - \frac{4}{5} - \frac{5}{5} \\ \\ \LARGE{} \frac{1 - 4 - 5}{5} \\ \\ \LARGE{} \frac{ - 8}{58 } \\ \\ \LARGE{}\LARGE\boxed{ - \: \frac{8}{5} }$

C)

$\LARGE{} \frac{1}{5} - \frac{4}{5} + \frac{5}{5} \\ \\ \LARGE{} \frac{1 - 4 + 5}{5} \\ \\ \LARGE{}\LARGE\boxed{ \frac{2}{5} }$
