Answer 3

To solve the expression, let's first convert all the mixed fractions into improper fractions and then perform the operations step by step:

Step 1: Convert mixed fractions to improper fractions 20 16/25 = (20 * 25 + 16)/25 = (500 + 16)/25 = 516/25 13 9/25 = (13 * 25 + 9)/25 = (325 + 9)/25 = 334/25

23 4/14 = (23 * 14 + 4)/14 = (322 + 4)/14 = 326/14 7 13/14 = (7 * 14 + 13)/14 = (98 + 13)/14 = 111/14

Step 2: Perform the subtraction operation (516/25 + 334/25) - (326/14 + 111/14)

Step 3: Find a common denominator for both sets of fractions. The least common multiple of 25 and 14 is 350. So, we rewrite the fractions with a common denominator of 350.

[(516/25 * 14/14) + (334/25 * 14/14)] - [(326/14 * 25/25) + (111/14 * 25/25)]

Step 4: Simplify the fractions (14 * 516 + 14 * 334) / 350 - (25 * 326 + 25 * 111) / 350

Step 5: Perform the addition and subtraction of the fractions (7224 + 4676) / 350 - (8150 + 2775) / 350

Step 6: Continue simplifying (11900) / 350 - (10925) / 350

Step 7: Perform the final subtraction (11900 - 10925) / 350

Step 8: Simplify the result (975) / 350

Step 9: Reduce the fraction to the simplest form (if possible) 975 ÷ 25 = 39

The final result is: 39/14 or 2 11/14
