Answer 3

To solve the expression (4 5/7 - 1 17/14) * 4 2/3 + (3 2/9 - 1 5/6) * 18/25 ÷ 2 3/4, you can follow these steps:

Step 1: Convert mixed numbers to improper fractions. 4 5/7 = (4 * 7 + 5) / 7 = (28 + 5) / 7 = 33/7 1 17/14 = (1 * 14 + 17) / 14 = (14 + 17) / 14 = 31/14 4 2/3 = (4 * 3 + 2) / 3 = (12 + 2) / 3 = 14/3 3 2/9 = (3 * 9 + 2) / 9 = (27 + 2) / 9 = 29/9 1 5/6 = (1 * 6 + 5) / 6 = (6 + 5) / 6 = 11/6 2 3/4 = (2 * 4 + 3) / 4 = (8 + 3) / 4 = 11/4

So the expression becomes:

(33/7 - 31/14) * (14/3) + (29/9 - 11/6) * (18/25) ÷ (11/4)

Step 2: Perform the operations within each set of parentheses.

(33/7 - 31/14) = (94/14 - 31/14) = 63/14 (29/9 - 11/6) = (58/18 - 33/18) = 25/18

So the expression is now:

(63/14) * (14/3) + (25/18) * (18/25) ÷ (11/4)

Step 3: Simplify further.

(63/14) * (14/3) = (63/14) * (14/3) = 63/3 = 21 (25/18) * (18/25) = 25/25 = 1

Now the expression becomes:

21 + 1 ÷ (11/4)

Step 4: Divide by the fraction.

1 ÷ (11/4) = 1 * (4/11) = 4/11

So the final result is:

21 + 4/11
