Question

1) Resolva as operações e simplifique os resultados.



A) 3/10 + 2/6=

B) 1/5 - 1/6=




C)2/5+3/5=

D)5/7+2/4

E) 2+ 3/5=

F) 5/2-6/10=

Answer 1

Explicação passo-a-passo:

A) 3/10+2/6 m.m.c=30

(9+10)/30=

19/10 =

1,9

B)1/5-1/6 m.m.c =30

(6-5)/30=

1/30

C)2/5+3/5=

(2+3)/5

5/5=1

D)5/7+2/4 m.m.c =28

(20+14)/28=

34/28 :(2/2)=17/14

E)2+3/5 m.m.c =5

(10+3)/5=13/5

F)5/2-6/10 m.m.c =10

(25-6)/10= 19/10=1,9
