Answer 2

To perform these multiplications, we'll convert the mixed numbers into improper fractions, then multiply the fractions, and finally simplify the result if necessary.

1. 2 1/3 * 1 1/2:

First, convert the mixed numbers into improper fractions: 2 1/3 = (2 * 3 + 1)/3 = 7/3 1 1/2 = (1 * 2 + 1)/2 = 3/2

Multiply the fractions: (7/3) * (3/2) = (7 * 3)/(3 * 2) = 21/6 = 7/2

The product is 7/2.

2. 3 1/5 * 3 3/4:

Convert the mixed numbers into improper fractions: 3 1/5 = (3 * 5 + 1)/5 = 16/5 3 3/4 = (3 * 4 + 3)/4 = 15/4

Multiply the fractions: (16/5) * (15/4) = (16 * 15)/(5 * 4) = 240/20 = 12

The product is 12.

3. 7 1/2 * 3 1/5:

Convert the mixed numbers into improper fractions: 7 1/2 = (7 * 2 + 1)/2 = 15/2 3 1/5 = (3 * 5 + 1)/5 = 16/5

Multiply the fractions: (15/2) * (16/5) = (15 * 16)/(2 * 5) = 240/10 = 24

The product is 24.

4. 3 1/9 * 1 2/7:

Convert the mixed numbers into improper fractions: 3 1/9 = (3 * 9 + 1)/9 = 28/9 1 2/7 = (1 * 7 + 2)/7 = 9/7

Multiply the fractions: (28/9) * (9/7) = (28 * 9)/(9 * 7) = 252/63 = 4

The product is 4.

Therefore, the results are:

1. 2 1/3 * 1 1/2 = 7/2
2. 3 1/5 * 3 3/4 = 12
3. 7 1/2 * 3 1/5 = 24
4. 3 1/9 * 1 2/7 = 4
