Final answer:
A quire of paper contains 25 sheets, calculated by taking 1/20th of a ream, which contains 500 sheets.
Step-by-step explanation:
When we are asked how many sheets of paper are in a quire, we can calculate this based on the fact that a ream of paper contains 500 sheets. A quire is defined as 1/20th of a ream. To find out how many sheets are in a quire, we can set up a simple mathematical proportion.
To determine the number of sheets in a quire, we use the ratio:
1 quire/1 ream = 1/20/500, where 1 ream is equivalent to 500 sheets. Solving for the number of sheets in a quire results in:
1 quire = 500 sheets × (1/20) = 25 sheets.
Thus, a quire of paper contains 25 sheets.
