Question

faça as operações com as frações:
A) 4/5+7/5=
B) 1/4+3/4=
C) 2/7+3/7=
D) 2/3+1/4=
E) 3/4+2/5=
F) 7/8-3/4=
g) 13/8-5/4=
h)1/3+2/5-1/6​

Answer 1

A) 4/5+7/5= 11/5

$\frac{4}{5} + \frac{7}{5} = \frac{11}{5}$

B) 1/4+3/4= 1

$\frac{1}{4} + \frac{3}{4} = 1$

C) 2/7+3/7= 5/7

$\frac{2}{7} + \frac{3}{7} = \frac{5}{7}$

D) 2/3+1/4= 11/12

$\frac{2}{3} + \frac{1}{4} = \frac{11}{12}$

E) 3/4+2/5= 23/20

$\frac{3}{4} + \frac{2}{5} = \frac{23}{20}$

F) 7/8-3/4= 1/8

g) 13/8-5/4= 3/8

h)1/3+2/5-1/6 = 17/30
