Answer 2

To solve this expression, you can follow these steps:

Step 1: Convert mixed numbers to improper fractions.

• 4 3/5 can be converted to an improper fraction as (5 * 4 + 3) / 5 = 23/5.
• 2 3/7 can be converted to an improper fraction as (7 * 2 + 3) / 7 = 17/7.
• 2 2/5 can be converted to an improper fraction as (5 * 2 + 2) / 5 = 12/5.

So, the expression becomes:

(23/5) * (17/7) + (12/5) * (17/7)

Step 2: Multiply the fractions. (23/5) * (17/7) = (23 * 17) / (5 * 7) = 391/35 (12/5) * (17/7) = (12 * 17) / (5 * 7) = 204/35

Step 3: Add the results. (391/35) + (204/35) = (391 + 204) / 35 = 595/35

Step 4: Simplify the fraction. 595/35 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5: (595 ÷ 5) / (35 ÷ 5) = 119/7

So, the final result is 119/7.
