Answer 2

To subtract mixed fractions, you can follow these steps:

Step 1: Convert the mixed fractions to improper fractions. Step 2: Subtract the two improper fractions. Step 3: If the result is an improper fraction, convert it back to a mixed fraction (if desired).

Let's apply these steps to the given problem:

Step 1: Convert the mixed fractions to improper fractions.

21 4/8 = (21 * 8 + 4)/8 = 172/8 14 7/8 = (14 * 8 + 7)/8 = 119/8

Step 2: Subtract the two improper fractions.

Result = (172/8) - (119/8) = (172 - 119)/8 = 53/8

Step 3: Convert the result back to a mixed fraction (if desired).

53/8 = 6 5/8

So, 21 4/8 − 14 7/8 = 6 5/8 mixed fractions.
