Answer 2

To solve these calculations, we'll convert the mixed numbers into improper fractions and then perform the multiplications.

1. 5 2/5 • 2 2/9: Convert 5 2/5 to an improper fraction: (5 * 5 + 2) / 5 = 27/5 Convert 2 2/9 to an improper fraction: (2 * 9 + 2) / 9 = 20/9 Multiply the fractions: (27/5) * (20/9) = (27 * 20) / (5 * 9) = 540/45 = 12

2. 18/25 • 3 3/4 • 8/9: Convert 3 3/4 to an improper fraction: (3 * 4 + 3) / 4 = 15/4 Multiply the fractions: (18/25) * (15/4) * (8/9) = (18 * 15 * 8) / (25 * 4 * 9) = 2160/900 = 12/5 = 2 2/5

3. 9/11 • 4 1/30 • 3 1/3: Convert 4 1/30 to an improper fraction: (4 * 30 + 1) / 30 = 121/30 Convert 3 1/3 to an improper fraction: (3 * 3 + 1) / 3 = 10/3 Multiply the fractions: (9/11) * (121/30) * (10/3) = (9 * 121 * 10) / (11 * 30 * 3) = 33,330/9,990 = 37/11 = 3 4/11

So the results are:

1. 5 2/5 • 2 2/9 = 12
2. 18/25 • 3 3/4 • 8/9 = 2 2/5
3. 9/11 • 4 1/30 • 3 1/3 = 3 4/11
