Question

Calcule a fração irredutível,ou seja,simplifique o máximo possível.

A)25/10
B)36/100
C)6/9
D)32/56
E)42/72
F)98/210

Answer 1

A) 25: 5 = 5
    10: 5 = 2

B) 36 : 2 = 18: 2 = 9 
   100 : 2 = 50: 2 = 25

C) 6: 3 = 2
     9: 3 = 3

D) 32: 2 = 16: 4 = 4
     56: 2 = 28: 4 = 7

E) 42: 2 = 21: 3 = 7
     72: 2 = 36: 3 = 12

F)  98: 2 = 46
    210: 2 = 105

Answer 2

a) 25/10 (÷5) = 5/2
b) 36/100 (÷4) = 9/25
c) 6/9 (÷3) = 2/3
d) 32/56 (÷8) = 4/7
e) 42/72 (÷3) = 14/24 (÷2) = 7/12
f) 98/210 (÷2) = 49/105 (÷7) = 7/15
