Order these numbers smaller to biggest: 60%, 0.4, 1/5

In order to do this we have to get all the numbers into percent form.

60% = 60%
0.4 = 40%
1/5 = 0.2 = 20%

So, the order from smallest to biggest is 1/5, 0.4, and 60%.

I would start out by putting them all in decimal form to understand them
So 1/5 is equal to 0.2 which is the smallest
And then you have 0.4
Then the biggest is 60% which is really just 0.6.
