Max rode his bike 40 miles in 2 1/2 hours. which complex fraction can be used to calculate max’s average speed?
a. 40/ 5/2
b.2/5 / 40
c. 40 / 2/5
d.5/2 / 40
try your best,

40 / 5 / 4. We're dividing this fraction because all the other ones are incorrect.

40 / 5 = 8.
We're going to take the first step first. 40 / 5 will equal 8.

8 / 4 = 2.
Now we're taking the answer to the last equation and dividing that by the last number, 4. Which equals 2.

-You can't do 2 / 5/40 because it is a improper equation.
-40 / 2/5, we're able to do it but... How did they get 2/5 from 2  ?
-5/2 / 40, Again, Improper equation.

That would leave us to the correct answer, A) 40/ 5/2.

Hope this helps!~
