12815 - 7 + 715 + 15 = 13538
i meant what is 12 8/15 - 7 +7/15 + 15
To simplify the expression 12 8/15 - 7 + 7/15 + 15, we need to convert all the numbers to a common fraction format.
12 8/15 = (15*12 + 8)/15 = 152/15
7 + 7/15 = (15*7 + 7)/15 = 112/15
15 = 15/1
Now, we can rewrite the expression:
152/15 - 112/15 + 15/1
To add or subtract fractions, we need a common denominator. In this case, the common denominator is 15.
(152 - 112 + 15*15) / 15
Performing the calculations:
(152 - 112 + 225) / 15 = 265/15.
So, the simplified answer is 265/15.
