Real-Life Math -- Solution

1. What is the largest number of flyers you can get per sheet?

To find the most flyers per sheet, divide the length and width of the large sheet by the length and width of the small sheet.

Big Sheet Width / Small Sheet Width
25 / 5.5 = 4.55

Big Sheet Length / Small Sheet Length
38 / 8.5 = 4.47

Now round it off because you can't have half sizes.

5 x 4 = 20

This way, you get 20 flyers per sheet.

Now reverse it.

Big Sheet Length / Small Sheet Width
38 / 5.5 = 6.91

Big Sheet Width / Small Sheet Length
25 / 8.5 = 2.94

Now round it off because you can't have half sizes.

7 x 3 = 21

This way, you get 21 flyers per sheet. Therefore, the most you can get is 21 flyers per sheet.

2. How much paper, in square inches, is left over per sheet?

To find out how much paper is left over, calculate the total area of the big sheet minus the total area of the 16 sheets.

Area of big sheet

38 x 25 = 950 square inches

The size of a sheet is 950 square inches.

Area of the 16 flyers
5.5 x 8.5 x 16 = 748 square inches

The area of the flyers is 748 square inches.

950 - 748 = 202 square inches

For each sheet, 202 square inches of paper are wasted.

3. If you print 4,800 flyers, how many sheets of paper will you use? How much paper, in square inches, will be wasted?

4,800 / 16 = 312.5

You will use 300 sheets.

300 x 202 square inches = 60,600 square inches

You will waste 60,600 square inches of paper. Of course, it will all be recycled!

Printing machine operators use math for problems like the one above. If this problem was easy for you, your math skills are already strong enough for this career.

"You've got to use a bit of math," says printing machine operator Graham Pratt. "You're using add and subtract, multiply and divide. It's not trigonometry or anything like that. It's just basic skills."

Printing machine operators often count large numbers of pages. Being able to count quickly and remember numbers comes in handy.

Most printing machines use imperial measurements. However, some of the newer presses work with metric as well. Therefore, it's also useful to be able to convert metric measurements to imperial, and vice-versa.
