d)4 1/7
e)2 1/2
f)3 6/7
g)6 1/2
h)7 4/9

Answer 1

a)1  2/3 = 3 x 1 + 2/3 = 3 + 2 /3 = 5/3
b)2  2/5 = 5 x 2 + 2 /5 = 10 + 2/5 = 12/5
c)5  3/4 = 4 x 5 + 3 /4 =  20 + 3 / 4 = 23/4
d)4  1/7 = 7 x 4 + 1 /7 = 28 + 1 /7 = 29/7
e)2  1/2 = 2 x 2 + 1 /2 = 4 + 1 / 2 = 5/2
f)3   6/7 = 7 x 3 + 6/7 = 21 + 6/7 = 27/7
g)6  1/2 = 2 x 6 + 1 /2 = 12 + 1 /2 = 13/2
h)7  4/9 = 9 x 7 + 4/9 = 63 + 4 /6 = 67/9 

Answer 2

Resposta:

a)1  2/3 = 3 x 1 + 2/3 = 3 + 2 /3 = 5/3

b)2  2/5 = 5 x 2 + 2 /5 = 10 + 2/5 = 12/5

c)5  3/4 = 4 x 5 + 3 /4 =  20 + 3 / 4 = 23/4

d)4  1/7 = 7 x 4 + 1 /7 = 28 + 1 /7 = 29/7

e)2  1/2 = 2 x 2 + 1 /2 = 4 + 1 / 2 = 5/2

f)3   6/7 = 7 x 3 + 6/7 = 21 + 6/7 = 27/7

g)6  1/2 = 2 x 6 + 1 /2 = 12 + 1 /2 = 13/2

h)7  4/9 = 9 x 7 + 4/9 = 63 + 4 /6 = 67/9
