12 8/15 - 7+ 7/15+15

Answer 1

To solve this expression, we need to find a common denominator for the fractions involved: 15.

First, we change the mixed numbers to improper fractions:
12 8/15 = 12 + 8/15 = 180/15 + 8/15 = 188/15
7 + 7/15 = 105/15 + 7/15 = 112/15

Now, we can subtract these two fractions:
188/15 - 112/15 = (188 - 112)/15 = 76/15

Finally, we add the result to 15:
76/15 + 15 = (76 + 225)/15 = 301/15

So, 12 8/15 - 7 + 7/15 + 15 = 301/15.
