3/10
1/10 + 2/5 = 1/10 + 4/10 = 5/10 = 1/2
5/10 + 1/2 = 1
1/2 = 5/10 so then 5/10 - 3/10 = 2/10 = 1/5
1/5 - 1/10 = 2/10 - 1/10 = (2 - 1)/10 = 1/10
1/5 x 2/2 = 2/10 2/10 + 3/10 = 5/10 = 1/2
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
1/5 + 3/10 = 2/10 + 3/10 = 5/10 = 1/2
1/5 = 2/10Therefore 2/10 + 1/10 = 3/10
It is: 2/10 = 1/5
5 over 10 is 1 over 2
1 over 5 (1/5) = 2 over 10 (2/10) = 20 over 100 (20/100) =
1/10 is less than 2/5
