Answer 2

Let's break down the calculation step by step:

1. First, multiply the mixed numbers: 4 2/3 * 1 2/7

   To multiply mixed numbers, convert them to improper fractions and then multiply: (4 * 3 + 2) / 3 * (1 * 7 + 2) / 7

   (14/3) * (9/7)

2. Multiply the fractions: (14/3) * (9/7)

   To multiply fractions, multiply the numerators together and the denominators together: (14 * 9) / (3 * 7)

   (126/21)

3. Simplify the fraction: Divide both the numerator and denominator by their greatest common divisor, which is 3: (126 ÷ 3) / (21 ÷ 3)

   (42/7) = 6

So, 4 2/3 * 1 2/7 equals 6.

Now, let's continue with the next part of the calculation:

3. Multiply 5/8 * 4/5

   To multiply fractions, multiply the numerators together and the denominators together: (5/8) * (4/5) = (5 * 4) / (8 * 5) = 20/40

4. Simplify the fraction: Divide both the numerator and denominator by their greatest common divisor, which is 20: (20 ÷ 20) / (40 ÷ 20) = 1/2

So, 5/8 * 4/5 equals 1/2.

Now, let's move on to the final part of the calculation:

5. Multiply 9/25 * 2 1/7 * 1 5/9

   First, convert the mixed numbers to improper fractions: 2 1/7 = (2 * 7 + 1) / 7 = 15/7 1 5/9 = (1 * 9 + 5) / 9 = 14/9

   Now, multiply the fractions: (9/25) * (15/7) * (14/9)

6. Multiply the fractions together: (9/25) * (15/7) * (14/9)

   To multiply fractions, multiply the numerators together and the denominators together: (9 * 15 * 14) / (25 * 7 * 9)

7. Simplify the fraction: Divide both the numerator and denominator by their greatest common divisor, which is 9: (9 ÷ 9) * (15 * 14) / (25 * 7 * 9)

   (1/1) * (15 * 14) / (25 * 7 * 1)

   (15 * 14) / (25 * 7)

8. Further simplify the fraction: Divide both the numerator and denominator by their greatest common divisor, which is 7: (15 * 14) / (25 * 7)

   (15 * 2) / (25 * 1)

   (30/25)

9. Simplify the fraction: Divide both the numerator and denominator by their greatest common divisor, which is 5: (30 ÷ 5) / (25 ÷ 5)

   (6/5)

So, 9/25 * 2 1/7 * 1 5/9 equals 6/5.
