Answer 1

Resposta:

a) 5/4

b) 2/7 + 3/4 = 8/28 + 21/28 = 29/28

c) 1/2 + 3/5 = 5/10 +6/10 = 11/10

d) 1/3 x 3/6 = 3/18 = 1/6

e) 6/2 x 4/5 = 24/10 = 12/5

f) 2/5 : 6/8 = 2/5 * 8/6 = 16/30 = 8/15

g) 4/3 + 1/2 = 8/6 + 3/6 = 11/6

h) 1/2 + 3/4 = 4/8 + 6/8 = 10/8 = 5/4

i) 3/6 - 6/8 = 1/2 - 3/4 = 4/8 - 6/8 = - 2/8 = -1/4

j) 3/5 * 6/9 = 18/45 = 2/5

k) 4/6 : 7/2 = 4/6 * 2/7 = 8/42 = 4/21

l) 6/4 : 3/5 = 6/4 * 5/3 = 30/12 = 5/2

m) 6/9 - 7/8 = 48/72 - 63/72 = - 15/72 = -5/24
