Question

Calcule e simplifique o resultado quando for possível

5/9+1/9=

1/4-1/8=

1/3+1/6+1/12=

4/5+1/2-5/8

Answer 1

Olá, bom dia ☺

Resoluções:

1)

5/9+1/9 = ( 5 + 1)/9=6/9 : 3/3=2/3.

2)

1/4-1/8 

m.m.c(4,8)=8.

(2 - 1)/8=1/8.

3)

1/3+1/6+1/12

m.m.c(3,6,12)=12.

(4 + 2 + 1)/12=7/12

d)

4/5+1/2-5/8

m.m.c(2,5,8)=40

(32 + 20 - 25)/40=27/40

Bons estudos :)
