Suppose that Barry Bonds has 148 hits in 500 at bats. How many hits does he need in his next 10 at bats to raise his batting average to .300?

Let's set up a proportion, cross multiply and solve for x.
1/12 = x/112
12x = 112
x = 9.33 = 9.5 inches
0.3 * 500 = 150

I understand the first concept, but I can't make out how you figured out the second word problem. How did you get 0.3?

batting average is a per 1000. So 356 is really an average of .356

I think the problem states the next 10 at bats so 0.3 x 510 = 153 hits needed. He already has 148 so he needs 5 more hits in his next 10 at bats. Or did I miss something?
