(3 3/5-2 1/5) *5

Answer

To solve this, we need to convert the mixed numbers to improper fractions and then perform the subtraction and multiplication.

Step 1: Convert the mixed numbers to improper fractions: 3 3/5 = (35 + 3)/5 = 18/5 2 1/5 = (25 + 1)/5 = 11/5

Step 2: Perform the subtraction: 18/5 - 11/5 = (18-11)/5 = 7/5

Step 3: Perform the multiplication with 5: 7/5 * 5 = (7*5)/5 = 35/5 = 7

So, (3 3/5 - 2 1/5) * 5 = 7.
