Answer 1

This is just a simple division problem. To make your life easier, make them both into improper fractions, 254/5 and 4/1. Use reciprocals to multiply. 254/5 * 1/4. Then you get 127/10, which simplifies to 12 7/10 as your answer.

I hope this helped and did not confuse you!

Answer 2

Hey!

If Louisa biked 50 4/5 miles in 4 hours, you have to divide distance by time to find the unit rate

50 4/5 as a decimal is 50.8

$Unit-Rate = \frac{distance}{time}$

$\frac{distance}{time} = \frac{50.8}{4}$

$50.8\div 4 = 12.7$

$\framebox{12.7 miles per hour}$

$12.7 = 12 \frac{7}{10}$
