1/18 + 1/6 is 2/9
6/18 = 1/3
3 over 18 = 1/6
11/18 - 1/6 = 11/18 - 3/18 = 8/18 = 4/9
6 over 18 is reduced to 1/3
1/18 + 1/6 is 2/9
HCF(6, 18) = 6 so divide both by 6. 6/18 = 6/6 over 18/6 = 1 over 3 = 1/3
1/6 + 3/18 = 1/3
8/18 plus 1/6 = 11/18
6/18 = 1/3
3 over 18 = 1/6
18
11/18 - 1/6 = 11/18 - 3/18 = 8/18 = 4/9
Divide the 6 and the 18 by 6 which equals one over three (1/3rd)
6 over 18 is reduced to 1/3
1/3 = 6/18 6/18 is bigger than 5/18 .
1/9 - 5/6 = 2/18 - 15/18 = - 13/18
