Answer 1

2/5+1/8-3/5+1/8-1/6


5 5
5 1
5=5

8 2
4 2
2 2
8=2^3

6 2
3 3
6=2x3

Mcd=2^3x3x5=120


2/5+1/8-3/5+1/8-1/6
48/120+15/120-72/120+15/120-20/120
-14/120
-7/60

Answer 2

Respuesta:

= $\frac{-7}{60}$

Explicación paso a paso:

$\frac{2}{5} + \frac{1}{2}$ × $\frac{1}{4} -\frac{3}{5} +\frac{1}{8} -\frac{1}{3}$ × $\frac{1}{2} =$

$\frac{2}{5} +\frac{1}{8} -\frac{3}{5} + \frac{1}{8} -\frac{1}{6} =$ $\frac{48+15-72+15-20}{120} = \frac{-14}{120} = \frac{-7}{60}$
