Answer:
4 feet or 4/15
Explanation:
1. So first you have to multiply the top and bottom number of each fraction by the denominator of the opposite fraction to have the same denominator:
1/3 X 5/5 = 5/15
3/5 X 3/3 = 9/15
2. Then you compare the two fractions and subtract the smaller fraction from the bigger:
9/15 - 5/15 = 4/15
