B) (-3/5)+(-1/4)=
C) 1/2-(1/4 - 1/8)=

Answer 1

Olá!

A)

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

B) (-3/5) + (-1/4) = -3/5 + (-1/4) = -3/5 - 1/4 = -17/20

C)

$\frac{1}{2} - ( \frac{1}{4} - \frac{1}{8} ) = \frac{1}{2} - \frac{1}{8} = \frac{3}{8}$

espero ter ajudado, bons estudos ;)
