Acomputer printer can print a 660-word document in 35 seconds. at this rate, how many seconds are required to print a document that contains 840 words?

Set up a proportion:

The numerator represents the words in the document, and the denominator represents the seconds it takes to print the document.

You can simplify the first fraction to make multiplication easier. Divide both the numerator and denominator by 5:

Cross multiply both fractions:

Divide both sides by 132 to get x by itself:

It will take 44.54 seconds to print the 840-word document.
