Question

Calcule

A) 3/4 - 1/6 B) 7/10+3/5 = C) 1/2 + 1/3 = D) 5 /9 + 1/3= E) 3/4 - 1/4 =

F) 5/4 + 2/6 + 4/5 = G) 10/3 + 1/5 + 2/3 =

Answer 1

A) 3/4 - 1/6 = (9-2)/12 = 7/12

B) 7/10+3/5 =  (7+6)/10 = 13/10

C) 1/2 + 1/3 =  (3+2)/6 = 5/6

D) 5 /9 + 1/3= (5+3)/9 = 8/9

E) 3/4 - 1/4 = 2/4 ou 1/2

F) 5/4 + 2/6 + 4/5 = (75+20+48)/60 =  143/60

G) 10/3 + 1/5 + 2/3 = (50+3+10)/15 =   63/15 ou  21/5
