Answer: 1 2/3 ; 255 minutes
Molly read 75 pages in 45 minutes. If we divided 75 into 45, we can figure out how many pages she read in 1 minutes. 75/ 45 is 1.66666667.
1.66666667 as a fraction is 1 and 2/3. This means in 1 minute Molly will read 1 page and 2/3rd's of a page. To figure out how long it will take for her to read 425, we can divide that into 1 2/3.
425/ 1.67 is 254.491018. That round to 254 minutes and 29 seconds. This is almost 255 minutes.
This means our unit rate is 1 2/3 and it will take 255 minutes to read the entire novel. To check we can divided 425 into 255 minutes-->
425/255 is 1.66666667, which once again equals 1 2/3
I hope this helped & Good Luck <3 !!
