The following transcript is provided for your convenience.

For example, 35% means 35 out of 100. So, you could express it as 35/100, which could then be simplified to 7/20.

You could also write 35 out of 100 as a decimal, 0.35.

So, percentages, again, are just that number out of 100.

Let’s take 85%. 85% means 85 out of 100, which can also be simplified to 17/20, and 0.85 can be written as a decimal, 0.85.

Percentages are closely related to both fractions and decimals. They are related to decimals because percentages break values into parts of one hundred (the denominator). Percentages are related to fractions because they represent values that are parts of a whole.

Don’t think that percentages are always smaller than one hundred. You may have percentages represent an increase of several hundred percents. Percentages can also go up or down. The percent change is always based on your original numbers.
