Answer 2

a)1/4 i 1/8

   2/8  i  1/8

 

b) 3/10 i 2/5 = (2*2) / (5*2) = 4/10

   3/10  i   4/10

 

c) 4/9 i 5/6

4/9 = (4*2)/(9*2) = 8/18

5/6 = (5*3) /(6 * 3) = 15/18

 

d) 5/8 i 7/12

5/8 = (5*3) / (8*3) = 15/24

7/12 = (7*2)/(12*2) = 14/24

 

e) 5/8 i 1/6

5/8 = (5*3)/(8*3) = 15/24

1/6 = (1*4)/(6*4) = 4/24
