It is: 7+13-6+5 = 19
-11
10/6 or 5/3
2/5 plus 1/3 plus 5/6 is equal to 1.57 or 1 57/100
I think the answer is 1625 [not the best in math might want to double check] [3over5 =6 6+7=13 13 over 8 = 8 divided by 13000]
5/13 + 6/11 = = 133/143
5/9 + 1/6 is 13/18
1.75 or 13/4
It is 2 13/18.
The sum of 3/14 and 13/21 is 5/6.
It is: 7+13-6+5 = 19
13/14 + 5/6 = 39/42 + 35/42 = 74/42 = 37/21 or 116/21
-11
It is: 5/6 minus 6/13 = 29/78
(5/6) / (13/12) = (5/6) x (12/13) = (5/1) x (2/13) = 10/13
10/6 or 5/3
1/10 + 5/6 + 2/3 = 3/30 + 25/30 + 20/30 = 48/30 = 16/10 or 13/5
