Answer 2

To subtract mixed numbers, we need to convert them into improper fractions and then perform the subtraction. Let's solve the problem step by step.

Step 1: Convert the mixed numbers into improper fractions. 15 1/2 = (2 * 15 + 1)/2 = 31/2 8 5/8 = (8 * 8 + 5)/8 = 69/8

Step 2: Subtract the fractions. 31/2 - 69/8

To subtract fractions with different denominators, we need to find a common denominator.

The least common multiple (LCM) of 2 and 8 is 8. Therefore, we need to convert the fractions to have a denominator of 8.

31/2 * (4/4) = 124/8 69/8

Now we can subtract the fractions:

124/8 - 69/8 = (124 - 69)/8 = 55/8

Step 3: Simplify the result, if necessary. 55/8 is already in its simplest form.

So, the result of the subtraction 15 1/2 - 8 5/8 is 55/8.
