12.5 or 12 1/2
if you mean 5 over 10 + 2 over 5, then your answer is 9 over 10.
5/10 + 1/2 = 1
1/10 + 2/5 = 1/10 + 4/10 = 5/10 = 1/2
3/5 + 2/10 = 6/10 + 2/10 = 8/10 = 4/5.
2/5 + 8/5 = 10/5 = 2
1/5 plus 1/5 which equals 2/5 or 0.4.
1/5 + 3/10 = 2/10 + 3/10 = 5/10 = 1/2
3/5 + 2/4 = 6/10 + 5/10 = 11/10
1/5 = 2/10Therefore 2/10 + 1/10 = 3/10
2
