This problem says a baseball player has a batting average of 250 or 0 .250, which means he gets a hit 25 % of the time.

He's a bat.
00:08
If he bats 450 times during the season, how many hits should he expect to get? so there's a couple different ways we could solve this.
00:15
First, since we're given the percentage that's equivalent to the batting average of 250, we can set that over 100, which is what all percentages are out of.
00:23
And then we could set that equal to x over 450, because if we know 100 % of us at bats is 450, 25 which represent the number of times he gets a hit, and then we could set those proportions equal, and then cross -multiply, and set our products equal and solve that way.

But a faster method would be to take the decimal version of our percentage, which was the original thing given to us, the 0 .250, and just multiply it by 450, because that will give us 25 % of 450...
