4/15 + 5/12 = 0.683 recurring (that is, 0.683333...)
the answer is 24. what you can do is: 5+3=8 8+4=12 12+3=15 15+10=25 25-1=24
5/6 = 10/12 + 5/12 = 15/12 = 5/4 or 1 1/4 or 1.25
7/12+8/12 = 15/12 15/12 = 5/4 or 1.25
1/3 + 5/4 = 4/12 + 15/12 = 19/12
one and a quarter 5/6 = 10/12 10/12 + 5/12 = 15/12 = 5/4 5/4 = 4/4 + 1/4 = 1 + 1/4
5/15 + 12/15 = 17/15 or 1 and 2/15
2/3 + 4/5 = 10/15 + 12/15 = 22/15
5/12 +4/9 = 15/36 = 16/36 = 31/36
-5+7--4+12 = 18
One and one fourth = 5/4. 5/4 plus 1/3 is impossible to do, so we must make common denominators. Multiply 5/4 by 3 and 1/3 by 4. 15/12 plus 4/12 = 19/12.
4/5+2/15=12/15+2/15=14/15
5 + 1 + 4 + 12 = 22
