Answer 3

To solve this expression, you need to add the fractions and whole numbers together. Here's the step-by-step solution:

1. Start with the fractions:

   • 3/5 + 3 3/4 + 1 2/5 + 1 1/4

2. Add the fractions first. To add fractions, you need a common denominator. In this case, the common denominator for 5, 4, and 4 is 20. Convert each fraction to have a denominator of 20:

   • 3/5 = (3/5) * (4/4) = 12/20
   • 3 3/4 = 3 + 3/4 = 12/4 + 3/4 = 15/4 = (15/4) * (5/5) = 75/20
   • 1 2/5 = 1 + 2/5 = 5/5 + 2/5 = 7/5 = (7/5) * (4/4) = 28/20
   • 1 1/4 = 1 + 1/4 = 4/4 + 1/4 = 5/4 = (5/4) * (5/5) = 25/20

3. Now, add the fractions:

   12/20 + 75/20 + 28/20 + 25/20

4. Combine the fractions:

   (12/20 + 75/20 + 28/20 + 25/20) = 140/20

5. Simplify the fraction:

   140/20 = (140/20) ÷ (20/20) = 7

So, the result of the expression is 7.
