Answer 2

To solve the expression, we need to perform the operations in the following order: addition and subtraction within parentheses first, and then the subtraction outside the parentheses.

Let's start by solving what's inside the innermost parentheses first:

8 7/60 - 3 3/4 + 8 7/25

To perform addition and subtraction, we need to find a common denominator for the fractions. The common denominator for 60, 4, and 25 is 300.

Converting each fraction to have a denominator of 300:

8 * (300/60) + 3 * (300/4) + 8 * (300/25) = 8 * 5 + 3 * 75 + 8 * 12 = 40 + 225 + 96 = 361

Now we have:

15 2/5 - 361

Next, we need to convert the whole number mixed with fractions into improper fractions:

15 2/5 = (5 * 15 + 2)/5 = (75 + 2)/5 = 77/5

Now the expression becomes:

77/5 - 361

To subtract these fractions, we need a common denominator, which is 5:

(77 - 361) / 5 = -284 / 5

The final result is -284/5.
