Answer 2

It seems like you've provided a mixed expression with a combination of absolute values, addition, subtraction, and fractions. Let's break it down step by step:

1. |15|: The absolute value of 15 is 15.
2. |-3|: The absolute value of -3 is 3.
3. |-5/8|: The absolute value of -5/8 is 5/8.
4. 3 1/5: This is a mixed number, which is equivalent to 16/5.

Now, let's put everything together:

|15| + |-3| + |-5/8| + 3 1/5

= 15 + 3 + 5/8 + 16/5

To add fractions with different denominators (8 and 5), you need to find a common denominator. The least common multiple of 8 and 5 is 40.

= (15 * 40/40) + (3 * 40/40) + (5/8 * 5/5) + (16/5 * 8/8)

= 600/40 + 120/40 + 25/40 + 128/40

Now, add the fractions:

= (600 + 120 + 25 + 128) / 40

= 873 / 40

So, the simplified result of the expression is 873/40. If you'd like, you can convert this fraction to a mixed number or decimal for a more familiar representation.
