Question

Calcule e simplifique, preciso de ajuda para resolver. Preciso do calculo:
23/7 + 1/3 – 2 + 1/6 =
4 2/3 – 1 ½ + 7/8 =

Answer 1

23/7 + 1/3 - 2 + 1/6 = 
m.m.c = 42
138/42 + 14/42 - 84/42 + 7/42 = 
152/42 - 84/42 + 7 /42 = 68/42  + 7/42 = 75/42 simplifica por  3 = 25/14

4 2/3   -   1  1/2  + 7/8 = 
4 x 3 + 2 / 3   - 1 x 2 + 1  / 2  + 7/8  = 
12 + 2 / 3  -  2 + 1 /2  + 7/8 = 
14/3  -  3/2   + 7/8  =  m.m.c = 24
112/24  -  36/24  +  21/24 = 
76/24 + 21/24 = 97/24
