How many times longer is the baby alligator 3/4 ft than the baby 2/15ft

1. Find common denominators so the common denominator is 60

2. Multiply the numerator by how much the denominator goes into the common denominator so 3 x 15 and 2 x 4

3. You get left with 45/60 - 8/60

4. Subtract the numerators to get 37/60

5. You can't simplify it so the final answer is 37/60

Wait is this subtractions or something else besides that
