Marcel reads 20 pages every other day Xion reads 8 pages every day Amber reads 56 pages every 7 days Francessca reads 55 pages every 5 days Which one of these will get to 350 pages first? State the number of days they will take to complete it.

Marcel reads 20 pages every 2 days.

Then, in one day, she reads:

20/2 = 10 pages per day.

Now, we know that in one day she reads 10 pages, then we can subdivide the number 350 in N groups of 10 pages, each one of these N groups needs one day to be read, then 350 pages will be read in N days:

N = 350/10 = 35 days.

Xion reads 8 pages per day.

Then to read 350 pages, he neds:

N = 350/8 = 43.75 days

Amber reads 56 pages in 7 days.

Then she reads 56/7 = 8 pages per day (Same as Xion)

Then she also needs 43.75 days to read 350 pages.

Francessca reads 55 pages in 5 days.

Then she reads 55/5 = 11 pages per day.

To read 350 pages, she needs:

350/11 = 31.82 days

Then the one that needs less days to read 350 pages is Francessca.
