Barnes and noble bookstore ordered 800 art books. on verifying the order , only 160 books were actually received . the percent of the order missing was

If you would like to know the percent of the missing order, you can calculate this using the following steps:

800 books - 160 books = 640 missing books
x% of 800 art books is 640 missing books
x% * 800 = 640
x/100 * 800 = 640
x * 8 = 640     /8
x = 640/8
x = 80%

The correct result would be: 80% missing books.

31/6= 19/6 19/6 *1/7=19/42
