How thick is a single sheet of paper? Assume you measure a ream of paper, which contains 500 sheets, and it is 2 1/4 inches thick. Let’s begin by setting

up a rate that compares the thickness to the number of sheets. Since we know 500 sheets has

a thickness of 2 1/4 inches, or 2.25 inches, we’ll set this up as 2.25

inches per 500 sheets. And now to determine the

thickness of one sheet, we want to find the unit rate which should be the number

of inches per one sheet, not 500 sheets. And therefore, we’ll divide both the numerator and denominator by 500. This will produce an equivalent unit rate. So 2.25/500 is equal to .0045 or 0.0045. This should be inches. Of course 500 divided by 500 is one. So this is the thickness per one sheet. So we can say the thickness

of one sheet of paper is 0.0045 inches. Next, how much does one

sheet of paper weigh? Assume a ream of 500

sheets weighs 5 pounds. We want to give the answer

in both pounds and ounces. So again we know that there

are 5 pounds per 500 sheets. Again our goal here is

to find the unit rate for the number of pounds per one sheet. So once again we’ll divide both the numerator and denominator by 500 to produce an equivalent unit rate. Our denominator is just

going to be 1 sheet. Our numerator is going to

be 5 divided by 500 pounds which will be .01 or 0.01 pounds. So each sheet weighs 0.01 pounds. We’re also asked to

convert this to ounces. To do this we’ll use the

conversion 16 ounces=1 pound. So if we have 0.01 pounds,

we can put this over 1 and multiply it by a unit fraction to perform this conversion. Because we want to eliminate pounds, our unit fraction will have

pounds in the denominator and ounces in the numerator. And the conversion is 16 ounces=1 pound. Notice here the units of

pounds simplifies out. Therefore this product will

give us the number of ounces in 0.01 pounds. There should be an L here. Well 0.01 times 16 is equal to 0.16. Therefore each sheet weighs

.01 pounds or 0.16 ounces. I hope you found this helpful.

" two and one fourth " you mean 2 and a quarter? This is the most complex rubbish I have ever seen. I assume American ?
