Answer 2

To solve the expression (3 1/7 + 2 1/3) ÷ (3 2/7), we can follow these steps:

Step 1: Convert the mixed numbers to improper fractions. - 3 1/7 can be written as (7 * 3 + 1) / 7 = 22/7 - 2 1/3 can be written as (3 * 2 + 1) / 3 = 7/3 - 3 2/7 can be written as (7 * 3 + 2) / 7 = 23/7

Step 2: Perform the addition and subtraction operations. - (22/7 + 7/3) = (66/21 + 49/21) = 115/21

Step 3: Perform the division operation. - (115/21) ÷ (23/7) = (115/21) * (7/23) = (115 * 7) / (21 * 23) = 805 / 483

Therefore, the result of the expression (3 1/7 + 2 1/3) ÷ (3 2/7) is 805/483.
