Answer:
[tex]\frac{127}{10} = 12.7[/tex]
Step-by-step explanation:
First, let's convert our mixed fraction 50 4/5, into an improper fraction. In order to do that, we can find an equivalent fraction to 50:
[tex]50 = \frac{50}{1} = \frac{250}{5}[/tex]
Now, adding the 4/5, we get
[tex]50 + 4/5 = \frac{250}{5} + 4/5 = \frac{254}{5} [/tex]
As we know how much she biked in four hours, we will divide it by 4, in order to get how much she biked in one hour.
[tex]\frac{254/5}{4} = \frac{245/5}{4/1}[/tex]
Now we divide these fractions. We can do that multiplying 254*1= 254 and 4*5=20 and dividing that:
[tex]\frac{254}{20}[/tex]
Finally, we have to simplify the fraction
[tex]\frac{254}{20} = \frac{127}{10}[/tex]
