Answer 2

To solve the expression, let's first convert the mixed numbers to improper fractions:

5/6 + 2 2/5 = 5/6 + (2 * 5 + 2) / 5 = 5/6 + 12/5

Now, find a common denominator, which is 30:

5/6 + 12/5 = (5 * 5) / (6 * 5) + (12 * 6) / (5 * 6) = 25/30 + 72/30

Combine the fractions:

25/30 + 72/30 = (25 + 72) / 30 = 97/30

Now, let's continue with the multiplication:

(97/30) × 7.5 = (97 × 7.5) / 30 = 727.5 / 30 ≈ 24.25

So, the result of the expression is approximately 24.25.
