DVD cases are 9/16" wide. If Juan has 60 DVDs, how many will fit on a 2 1/2 feet long shelf?
First convert feet to inches:
2 1/2 = 5/2 feet
5/2 feet * 12 inches / 1 foot = 30 inches
Then we divide this by 9/16 inch:
30 / (9/16)
= 30 * 16 / 9
= 160 / 3
= 53 1/3
We only need the whole number (because the number of DVDs cannot be a fraction or decimal). Therefore, 53 will only fit.
Hope this helps~ :3
30 x 16/9 =
simplify
30/3 = 10; 10 x 16 = 160; 160/3 = 53
9/3 = 3
Oh my god. Thank you sooooo much. This helps a ton!
53

it's not too hard.
5 * 2 1/2 = 25/2.
18 minus 25/2 = Answer.
