Answer 3

To solve this mixed number subtraction problem, you can follow these steps:

Step 1: Convert all the mixed numbers to improper fractions.

3 2/5 = (5 * 3 + 2)/5 = 17/5 4 1/5 = (5 * 4 + 1)/5 = 21/5 2 2/5 = (5 * 2 + 2)/5 = 12/5 3 4/5 = (5 * 3 + 4)/5 = 19/5

Now the problem becomes:

17/5 + 21/5 - 12/5 - 19/5

Step 2: Add and subtract the fractions:

(17/5 + 21/5) - (12/5 + 19/5)

Step 3: Add and subtract the fractions separately:

(38/5) - (31/5)

Step 4: Subtract the fractions:

(38/5) - (31/5) = 7/5

Step 5: Convert the result back to a mixed number:

7/5 can be written as 1 2/5

So, the final answer is 1 2/5.
