• how do you convert a percentage into a decimal? •  Move the imaginary decimal point two spaces to the left.
100% -> 1.00
50% -> 0.50
1% -> 0.01
You could also divide a percentage by 100 to get the decimal.
100%/100 is 1.00
50%/100 is 0.50
1%/100 is 0.01

Did you know that 1/4 means one divided by 4?

So to get our decimal, we need to divide one by four... but that is difficult without a calculator!

But... we know that 1/4 times 4 is one... so we need to add the same something four times... so here is what you do. Divide one hundred by four. Hear me out, okay?

So, basically what that is going to do is move the decimal place two times... so when you get your answer, move it two times again!

100 divided by 4 is 25 or 25.0

move the decimal to the left two times, and you get .25!
