g)2/7 ÷ 8/14 h)6/9 ÷ 4/15

ME AJUDEM POR FVOR!!!!!​

Answer 1

Resposta:

a) 2/7 + 10/7 = 12/7

b) 5/9 - 3/9 = 2/9

c) 1/2 + 2/3 = 3/6 + 4/6 = 7/6

d) 5/3 - 3/4 = 20/12 - 9/12 = 11/12

e) 7/6*32/21 = 16/9

f) 4/18 * 9/6 = 1/3

g) (2/7)/(8/14) = (14/8)*(2/7) = 1/2

h) (6/9)/(4/15) = (15/4)*(6/9) = 90/36 = 5/2
