Roger average 3 hits for every 12 times he is at bat at his. rate how many must he bat to hit 12 hits

He can hit 3 out of every 12 bats. This can be translated to 3/12. We want to make the numerator 12, so we multiple the top by 4, so we have to do the same thing on the bottom. This fraction would be 12/48.

He has to bat 48.
