Jeff and Mike are playing both playing an online game. There are 28 levels in the
game. Jeff is on level 15 and Mike is on
level 17. What percent of the game do
they each have left until they have
completed all levels?

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.
