Question

4. Richard can read of a book in of an hour. At this rate, how much can Richard read in one hour?

Answer 1

Richard can read (missing) of a book in (missing) of an hour.

Need something in those spots to find the exact answer, but in general if you just want to find his unit rate first turn the information into a fraction:

 

Books per hour = books/hour

 

Then divide the top by the bottom to find his unit rate (books per 1 hour).

For example:  If Richard could read half of a book in half of an hour that would be:

(1/2 book) / (1/2 hour) = 1 book per hour.

A little trickier: if he can read 1/8th of a book in 1/2 of an hour, then he can read:

(1/8) / (1/2) = 1/4

 

Not sure what kind of numbers you'll be dealing with (fractions, decimals, or whole), but if they're fractions remember that to divide fractions you keep the first one the same, change to multiplication, and then flip the second one over.  (Keep change flip!)

 

(1/8) / (1/2) = (1/8) * (2/1) = 2/8 = 1/4

 

Hope that helps!

 

Answer 2

Richard can read _____ of a book in _____ of an hour.

 

Let's use A for the first blank and B for the second blank (this seems to be the question being asked?)

If A is a proportion and B is a proportion then. ex: Richard can read 1/2 of a book in 1/2 of an hour.

The answer would be A*(1/B)
