Question

Calcule:
A) (3/4 + 1/2) - (1/2 - 1/6) + 1/8

Answer 1

5/4 - 2/6 + 1/8
11/12 + 1/8
25/24

Answer 2

Olá,boa tarde ☺

Resolução:

(3/4 + 1/2) - (1/2 - 1/6) + 1/8
(3+2/4)-(1/2-1/6) + 1/8   m.m.c(2,4)=4
(5/4) - (1/2 - 1/6) + 1/8
(5/4) - (3-1/6) + 1/8   m.m.c(2,6)=6
5/4 - 2/6 + 1/8

m.m.c(2,6,8)=24

30-8+3/24=25/24

Bons estudos :)
