Answer:5 3/8
Step-by-step explanation:
20 6/8 - 15 3/8 is 5 3/8
When you subtract a negative number it becomes an addition:
20 3/4 - -15 3/8 becomes:
20 3/4 + 15 3/8
Rewrite the fractions to have a common denominator:
3/4 = 6/8
Now you have 20 6/8 + 15 3/8
6/8 + 3/8 = 9/8 = 1 1/8
Now you have 20 + 15 + 1 1/8 = 36 1/8
The answer is 36 1/8
