Question

Calcule e Simplifique

a)1/5+2/3 d)5/6-1/3

b)5/6+2/3

c)9/2+7/4+2/3

Answer 1

a) 1/5 + 2/3 m.m.c=15
>> 3 + 10/15
>> 13/15

b) 5/6 + 2/3 m.m.c=6
>> 5 + 4 /6
>> 9/6 (÷3)
>> 3/2

c) 9/2 + 7/4 + 2/3 m.m.c(2,4)=4
>> 18 + 7/4 + 2/3
>> 25/4 + 2/3 m.m.c(4,3)=12
>> 75 + 8 /12
>> 83/12

d) 5/6 - 1/3 m.m.c(6,3)=6
>> 5 - 2 / 6
>> 3/6 (÷3)
>> 1/3
