YSK - X percent of Y is equal to Y percent of X. So, if you want to find out what 7% of 50 is, you could instead find out what 50% of 7 is, which is 3.5. This means that 7% of 50 is also equal to 3.5.

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”.
