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.
