Ratios and proportions are fractions. Remember equivalent fractions? 1/2 =2/4=5/10=14/28 Well ratios are fractions, and since they're usually maintained, you can compare different values as long as you keep the same ratio. Do you have a specific problem to look at?

um, 18/20 K/110... it says to use cross products! What is that?

So your ratio is 18/20 and since a ratio is maintained, you can say that it equals k/110 so: \[\frac{18}{20}=\frac{k}{110}\] Which you can solve as any equation. To isolate k, multiply times 110 on both sides. \[\frac{18*110}{20}=\frac{k*110}{110}\] \[\frac{18*110}{20}=k\]

Just remember a ratio is maintained. So you can equate the ratios given, no matter the change in the amount... Like unit prices. If someone says a quart of oil is 3.25 how many can you buy with 22.75 Well the fraction is: \[\frac{quarts of oil}{price}=\frac{1}{3.25}=\frac{x  quarts}{22.75}\] Hope that helps. Let me know if you have any you're stuck on, I may take time to answer, but I will.
