A bookshelf is 3 ½ feet long. Each book on the shelf in ⅝ inches wide. How many books will fit on the shelf?

5 books.

Step-by-step explanation:

You must divide 3 1/2 by 5/8. To do this, switch 3 1/2 to an improper fraction (7/2) and multiply by the reciprocal.

7/2  x  8/5  =  56/10.

56/10 can be simplified to 5 6/10, which can then be simplified to 5 3/5. Thus, your answer would be 5 3/5, but you cannot fit 3/5 of a book on a bookshelf since you'd have to cut 2/5 of the book off and that's not logical. So, your answer would be 5 books, and you'd have 2/5 inches of space left over.

Divide the width of the shelf by the widthof the books.

First rewrite feet as inches:

1 foot = 12 inches.

3 1/2 feet x 12 inches per foot = 42 inches

Now divide the width of the shelf by the width of the book:

Now you have 42  /  5/8

When dividing by a fraction flip the second fraction over and change division to multiplication:

42 x 8/5

Now Multiply across:

7/2 x 8/5 = (42 x 8) /5 = 336/5 = 67.2

Round to the nearest whole number: 62

The shelf will hold 62 books.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
