When Bruce started bowling, he won 1/4 of the games he played. Within six months, he was winning 7/16 of his games. If he improves at the same rate, what fraction of his games should he expect to win after another six months?


I subtracted the 1/4 from 7/16 and came up with 3/16 for the first 6 months. Then I added the 7/16 for the next 6 months and came up with 10/16 or 5/8. I know this is not correct.

What am I doing wrong?

While there may be more than one interpretation of what "the same rate" means, under the most reasonable interpretation I get the same answer you got (5/8).

Which leads me to ask, why do you say that you "know this is not correct"? Do you have an answer key that gives a differing answer?
No, I don't. I just didn't think you should subtract the 1/4 from the first 6 months.
