Answer 2

To solve the given expression, follow the order of operations (PEMDAS/BODMAS):

1. Start with the operations inside the parentheses.
2. Perform the division and multiplication from left to right.
3. Finally, do the addition and subtraction from left to right.

Given expression: 5/9 + 1 5/7 × (4 2/3 - 2 5/8) ÷ 1 3/4

Step 1: Solve the operations inside the parentheses. 4 2/3 - 2 5/8 = (4 + 2/3) - (2 + 5/8) = 4 2/3 - 2 5/8 = 4 2/3 - 2 5/8

Step 2: Convert mixed numbers to improper fractions (if needed). 4 2/3 = (4 * 3 + 2) / 3 = 14/3 2 5/8 = (2 * 8 + 5) / 8 = 21/8

Step 3: Perform the subtraction inside the parentheses. 14/3 - 21/8 = (14 * 8 - 21 * 3) / (3 * 8) = (112 - 63) / 24 = 49 / 24

Step 4: Move on to the multiplication and division. 1 5/7 × (49/24) ÷ 1 3/4

Step 5: Convert mixed numbers to improper fractions (if needed). 1 5/7 = (1 * 7 + 5) / 7 = 12/7 1 3/4 = (1 * 4 + 3) / 4 = 7/4

Step 6: Perform the multiplication and division. (12/7) × (49/24) ÷ (7/4)

Step 7: Simplify the expression by canceling common factors. (12 * 49) / (7 * 24) ÷ (7/4) 588 / 168 ÷ (7/4)

Step 8: Divide the fractions. (588 / 168) * (4 / 7)

Step 9: Simplify the fraction. (7/2) * (4 / 7) = 4/2 = 2

Step 10: Add the remaining fraction to the result. 5/9 + 2 = 5/9 + 18/9 = (5 + 18) / 9 = 23/9

So, the final result is 23/9.
