7/12 + 8/12 = 15/12 = 1 and 3/12 = 1 and 1/4
4/12 + 11/15 = 1 1/15
A = 12 and 4/5
The ratio of 15 over 12 is 5:4.
12 over 15.
2/4 + 4/6= 14/12 which equals to1 2/12 which equals 1 1/6.
12/15 = 4/5
Let's see.4*1/4*3= 4/12=========Yes.
4/5 - 8/15 = 12/15 - 8/15 = 4/15
13 ? 15
3/4 - 5/12 = 9/12 - 5/12 = 4/12 = 1/3.
