Answer 3

To solve the expression, we'll first convert the mixed numbers to improper fractions and then perform the addition:

Step 1: Convert the mixed numbers to improper fractions: 2 3/4 = (2 * 4 + 3) / 4 = 11/4 2 1/5 = (2 * 5 + 1) / 5 = 11/5

Step 2: Add the fractions: (11/4 + 11/5)

To add fractions, we need a common denominator. The least common multiple (LCM) of 4 and 5 is 20.

Step 3: Convert the fractions to have a common denominator of 20: (11/4) * (5/5) = 55/20 (11/5) * (4/4) = 44/20

Step 4: Add the fractions: (55/20 + 44/20) = 99/20

Step 5: Multiply by 16: (99/20) * 16 = 79.2

Therefore, the result of (2 3/4 + 2 1/5) * 16 is approximately 79.2.
