Daniel is reading a 200-page book. He
reads 40 pages of the book in 50 minutes.
If he reads for 80 minutes, how many
pages will he have left?
-7th grade math

Set up a ratio to find the number of pages read in 80 minutes:

40 pages/ 50 minutes = x pages/ 80 minutes

Cross multiply:

50x = 3200

Divide both sides by 50:

X = 3200/50

X = 64

He will read 64 pages in 80 minutes.

200 -64 = 136

There will be 136 pages left.
