Question 257571: I've done pretty good with ratios and proportions until I hit this one and I'm stumped. The question reads: A baseball players batting average is the ratio of number of hits to number of times at bat. A player has 10 hits out of 20 times at bat. How many consecutive times at bat must a hit be made to raise his average to .600?
I'm guessing that somehow I have to use his current average of .500 but I can't figure out how to set up the equation to get the .600.
Thanks for any help,
Laura
