Answer 2

1. To multiply 9 3/5 by 10/21: First, convert the mixed number to an improper fraction: 9 3/5 = (5 * 9 + 3) / 5 = 48/5 Then multiply the numerators and denominators: (48/5) * (10/21) = (48 * 10) / (5 * 21) = 480/105 Simplify the fraction if possible: 480/105 = 16/7

Therefore, 9 3/5 multiplied by 10/21 equals 16/7.

2. To multiply 3 11/12 by 9/94: First, convert the mixed number to an improper fraction: 3 11/12 = (12 * 3 + 11) / 12 = 47/12 Then multiply the numerators and denominators: (47/12) * (9/94) = (47 * 9) / (12 * 94) = 423/1128 Simplify the fraction if possible: 423/1128 = 141/376

Therefore, 3 11/12 multiplied by 9/94 equals 141/376.

3. To multiply 1 5/7 by 6 1/8: First, convert the mixed numbers to improper fractions: 1 5/7 = (7 * 1 + 5) / 7 = 12/7, and 6 1/8 = (8 * 6 + 1) / 8 = 49/8 Then multiply the numerators and denominators: (12/7) * (49/8) = (12 * 49) / (7 * 8) = 588/56 Simplify the fraction if possible: 588/56 = 147/14 = 10 7/14 = 10 1/2

Therefore, 1 5/7 multiplied by 6 1/8 equals 10 1/2.

4. To multiply 3 5/9 by 5 1/4: First, convert the mixed numbers to improper fractions: 3 5/9 = (9 * 3 + 5) / 9 = 32/9, and 5 1/4 = (4 * 5 + 1) / 4 = 21/4 Then multiply the numerators and denominators: (32/9) * (21/4) = (32 * 21) / (9 * 4) = 672/36 Simplify the fraction if possible: 672/36 = 56/3

Therefore, 3 5/9 multiplied by 5 1/4 equals 56/3.

5. To multiply 1 13/15 by 5/8 by 2 2/7: First, convert the mixed numbers to improper fractions: 1 13/15 = (15 * 1 + 13) / 15 = 28/15, 2 2/7 = (7 * 2 + 2) / 7 = 16/7 Then multiply the numerators and denominators: (28/15) * (5/8) * (16/7) = (28 * 5 * 16) / (15 * 8 * 7) = 2240/1680 Simplify the fraction if possible: 2240/1680 = 28/21

Therefore, 1 13/15 multiplied by 5/8 multiplied by 2 2/7 equals 28/21.

6. To multiply 2 1/4 by 16/27 by 4 1/3: First, convert the mixed numbers to improper fractions: 2 1/4 = (4 * 2 + 1) / 4 = 9/4, 4 1/3 = (3 * 4 + 1) / 3 = 13/3 Then multiply the numerators and denominators: (9/4) * (16/27) * (13/3) = (9 * 16 * 13) / (4 * 27 * 3) = 3744/324 Simplify the fraction if possible: 3744/324 = 116/9

Therefore, 2 1/4 multiplied by 16/27 multiplied by 4 1/3 equals 116/9.
