Answer 2

To simplify the expression 12 8/15 - 7 + 7/15 + 15, we need to convert the mixed numbers into improper fractions.

12 8/15 can be written as (12 * 15 + 8)/15 = 188/15.
Similarly, 7 can be written as 7/1, and 15 as 15/1.

Then, the expression becomes:

188/15 - 7/1 + 7/15 + 15/1

Next, we find a common denominator among the fractions, which is 15.

188/15 - 7/1 + 7/15 + 15/1 can be written as:

(188 - 7*15 + 7 + 15*15)/15

Simplifying the numerator further:

(188 - 105 + 7 + 225)/15 = (90 + 232)/15 = 322/15

Therefore, the simplified answer is 322/15.

Answer 3

Apologies for the mistake in the previous response.

Let's simplify the expression correctly.

To start, we simplify the mixed number 12 8/15 to an improper fraction:

12 8/15 = (12 * 15 + 8)/15 = 188/15

Now we can rewrite the expression:

188/15 - 7 + 7/15 + 15

To add or subtract fractions, we need a common denominator among all the fractions. In this case, the common denominator is 15.

Rewriting the expression with a common denominator:

(188 - 7*15 + 7 + 15*15)/15 = (188 - 105 + 7 + 225)/15 = 315/15

Finally, we simplify the fraction:

315/15 = 21

Therefore, the simplified answer is 21.
