Пошаговое объяснение:

7целых 1/2×2целых4/15=(15/2)×(64/15)=32

Answer 3

To solve the expression, we can follow these steps:

1. Convert the mixed numbers to improper fractions. 7 1/2 becomes (7 × 2 + 1) / 2 = 15/2. 2 4/15 becomes (2 × 15 + 4) / 15 = 34/15.

2. Multiply the two fractions together. (15/2) × (34/15) = (15 × 34) / (2 × 15) = 510/30.

3. Simplify the resulting fraction if possible. In this case, both the numerator (510) and the denominator (30) can be divided by 30. 510/30 = (510 ÷ 30) / (30 ÷ 30) = 17/1 = 17.

Therefore, 7 1/2 × 2 4/15 is equal to 17.
