Write the two ratios with the same kind of quantity in the same place: cups over people on both sides, or height over shadow on both sides. Then cross-multiply.
Flipping one ratio. Cups over people on one side and people over cups on the other gives a wrong answer that still looks reasonable.
Also called proportion word problems, ratio word problems, similar figures word problems or shadow problems.

Questions about these worksheets
Yes. Every proportion word problems sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.
Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.

Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.
That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the proportion word problems questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.
Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.
You pick from 2: proportion word problems and with fractions. Tick as many as you want and set how many of each, or let it spread them evenly.
Flipping one ratio. Cups over people on one side and people over cups on the other gives a wrong answer that still looks reasonable.
