Answer 3

It seems like you've written the numbers in a couple of different formats. Let's simplify the expression step by step:

1. Convert Mixed Number to Improper Fraction:

   • Convert -2 1/5 to an improper fraction:
     -2 1/5 = -11/5

2. Perform Addition:

   • 7 + (-11/5) + (-3.8)

3. Addition:

   • 7 + (-11/5) + (-3.8) = 7 - 11/5 - 3.8

4. Common Denominator for Fractions:

   • The common denominator for 5 and 1 is 5. So, we need to rewrite -11/5 as an equivalent fraction with a denominator of 5: -11/5 = -55/25

5. Final Calculation:

   • 7 - 55/25 - 3.8 = 7 - 2.2 - 3.8 = 1 - 3.8 = -2.8

So, the result of the expression 7 + (-2 1/5) + (-3.8) is approximately -2.8.
