A rabbits fur grows at the rate of 5/2 in per month

How many months will it take for the rabbits for her to grow 15/4 inches? Explain work

About 3 months because if you look at the numerator then it would take about 2.5 months because 5 x 3 is 15 but if you were looking at the bottom then it would be 2 months because 2x2 is 4 so it would take about 2.5 months to get to that length
