Hello there! An example problem for this could be: Emile is looking for a cell-phone plan. His two options are one that costs $40 up front, and costs $0.01 per text, represented by x. The second one is 15 dollars up front and costs $0.06 for each text message. Emile figures that for the first package he has to send 500 texts or more to make it less than the second one.
In fractions they had won 11/20 games. Then if you convert the fraction to a percent you would get 55% after multipling by 5/5 to get the denominator of 100.
