Why YSK: It helps when calculating percentages. If you want to find out what 2% of 20 is, do 20% of 2 instead and you’ll get 0.4. So, 2% of 20 also equals 0.4.

Or, 12% of 25 can be alternatively written out as 25% of 12 instead, which would be 3.

Explanation: Commutative Property. So, 0.07 times 50 will always equal 50 times 0.07

    Percentage is just a fancy form of decimal point. I just multiply them together then move decimal digit to the left twice.

      This is true for quite a few other things as well. For instance, “hertz” really just means “per second”. However, it’s easier to write/type “Hz” instead of “s^-1”.
