Answer 2

Let's break down the calculations step by step:

1. 8/13 × 4 1/3: First, convert the mixed number 4 1/3 to an improper fraction. 4 1/3 = 4 + 1/3 = 12/3 + 1/3 = 13/3 So, the expression becomes (8/13) × (13/3). Now, multiply the fractions: (8/13) × (13/3) = (8 × 13) / (13 × 3) = 104/39

2. 7/16 × 3: Simply multiply the fractions: (7/16) × 3 = (7 × 3) / 16 = 21/16

3. 8/63 × 56: Simplify by finding common factors between the numerator and denominator. In this case, you can simplify by dividing both the numerator and denominator by 7. (8 ÷ 7) / (63 ÷ 7) × 56 = (8/9) × 56 Now, multiply the fractions: (8/9) × 56 = (8 × 56) / 9 = 448/9

So, the results are as follows:

1. 8/13 × 4 1/3 = 104/39
2. 7/16 × 3 = 21/16
3. 8/63 × 56 = 448/9
