1. 1/2 - 3/10 =( 1/2 x 5/5) - 3/10 = 5/10 - 3/10 = 2/10 = 1/5
2. 3/5 - 1/4 = (3/5 x 4/4) - (1/4 x 5/5) = 12/20 - 5/20 = 7/20
3. 4/5 - 2/3 = (4/5 x 3/3) - (2/3 x 5/5) = 12/15 - 10/15 = 2/15
4. 7/10 - 3/6 = (7/10 x 3/3) - (3/6 x 5/5) = 21/30 - 15/30 = 6/30 = 1/5
5. 3/4 - 2/12 = (3/4 x 3/3) - 2/12 = 9/12 - 2/12 = 7/12
