This problem is asking us to convert 0 .45 % to a fraction.
00:05
So our trick for converting percents to fractions is all you have to do is get rid of the percent symbol, and then put the remaining value over 100.
00:16
So now we have a fractional equivalent of 0 .45%.
00:20
But we have a decimal in the numerator of a fraction, which is not what we want.
00:24
We want whole numbers on both the top and bottom.
00:27
So to get rid of that fraction, we're going to multiply.
00:31
Or rather to get rid of the decimal, we're going to multiply the top by 100.
00:35
And since we're multiplying the top by 100, we're also going to multiply the bottom by 100.
00:39
So this is going to give us a new fraction, 45 on the top, and 10 ,000 on the bottom.
00:46
Both are whole numbers, so we've solved that problem.
00:50
But now we have to do the final step, which is to simplify this fraction, if possible...
