4 goes into 20 5 times,

so you have 1/5 if you reduced it

1/5 is .20 or 20%

to check your work or for an easy way to do it, 1 divided by 5 or 4 divided by 20 which is also .20 or 20%
You can start by dividing both top and bottom by four, making it 1/5. From there you can do 1 divided by 5 making it a decimal of 0.2. Afterwards, move the decimal to places to the right and add an extra 0 making the percentage 20%.
