A unit rate is a special type of ratio (also called a single-unit rate). It will compare 1 unit of some quantity to a different number of units of a different quantity. Any ratio that is not a unit rate can be turned into one.
Jeff has about 46.43% left and smile had about 39.29% left.
I got this by putting the number of levels that had left in a fraction over the total number of levels aka 28. I then wrote that that fraction was equal to x/100 where x would be the percentage. I divided 100 by 28 to see how to get from 28 to 100 if we multiplied. I then took the answer from that and multiplied the number of levels left by that number (3.571428571428571) and rounded to the nearest hundredth.
Here is a graph with the equation you gave graphed on it.
The answer is 2/3 (i think ✨)
