Asked by Kaashif
How can you tell which fractions represent a umber that is less than 1% without doing any computation? .02/5, .2/5, 2/5, 2/50, 2/500.
I know the numbers less than 1% are .02/5 and 2/500, but how do you know without doing the computation

Convert the given fraction to an equivalent fraction with either 1 or 100 as the denominator.
We know that 1% = 1/100 = 0.01/1
So say,
0.2/5 = 0.004/1 < 0.01=1%
2/500 = 0.4/100 < 1/100 = 1%
etc.
