Answer 2

It looks like you've provided a series of mathematical expressions and numbers. Let's break down each step:

1. -3 3/5: This represents a mixed number, which is -3 3/5 in fractional form.
2. 2.7 + 2.7: This is an addition of two decimal numbers, both of which are 2.7.
3. 3 3/5: This is another mixed number, which is 3 3/5 in fractional form.

Let's perform the calculations step by step:

First, convert the mixed numbers to improper fractions:

• -3 3/5 = -18/5
• 3 3/5 = 18/5

Now, let's perform the calculations:

• -18/5 + 2.7 + 2.7 = -18/5 + 5.4

To add these fractions and decimals, we need to find a common denominator. In this case, the common denominator is 5:

• (-18 + 27) / 5 + 5.4 = 9 / 5 + 5.4

Now, add the fractions and the decimal:

• (9 + 27) / 5 + 5.4 = 36 / 5 + 5.4

Now, convert the fraction to a decimal:

• 36 / 5 ≈ 7.2

Finally, add the decimal to the previous result:

• 7.2 + 5.4 = 12.6

So, the final result of the expression is approximately 12.6.
