Question

Faça as frações simplificando elas quando possível:
a) -2 + 5/6 + 3/4 =
b) 7/8 -1 1/4 + 2/3 =
c) -1 1/4 - 1/3 + 3/2 =
d) 3/2 + 1/6 -2/3 =
e) 1/2 -1/3 + 3/2 =
(a/b = fração)

Answer 1

a) -2 + 5/6 + 3/4 =
-24+10+9/12 =
-5/2.

b) 7/8 - 1 1/4 + 2/3=
7/8 - 1 . 1/2 . 1/3=
7/8 - 1/6=
17/24.

c) -1 1/4 - 1/3 + 3/2=
-1/4 - 1/3 + 3/2=
11/12.

d) 3/2 + 1/6 - 2/3=
9 + 1 - 4/6=
6/6= 1.

e) 1/2 - 1/3 + 3/2=
3 - 2 + 9/6=
10/6=
5/3.
