Question

Maya reads 6 3/4 chapters in 1 7/8 hours

what is the unit rate in chapters per hour?
write your answer as a fraction or a mixed number in simplest form

Answer 1

3 3/5 chapters per hour
6 3/4 = 27/4
1 7/8 = 15/8
1. You turn those two numbers into a complex fraction which is 27/4/15/8
2. You then multiply by the reciprocal which is 8/15/8/15
3. The bottom cancels out leaving you with the top to solve
4. By cross canceling you have to do 27x4 and 2x15 which is 108/30
5. By diving 108/30 by 6/6 you get 18/5 which equals 3 3/5 as a mixed fraction

I hoped this helped :)

Answer 2

Answer:To find the unit rate in chapters per hour, we need to divide the number of chapters read by the amount of time it took to read them.

6 3/4 chapters / 1 7/8 hours = (64+3)/(18+7) chapters/hours

= (25/8) chapters/hours

To simplify this fraction, you can divide both the numerator and denominator by their greatest common factor which is 1.

25/8 chapters/hours = (25/8) chapters/hours

So the unit rate in chapters per hour is 25/8 chapters per hour.
