PERCENTAGE & DECIMAL REVIEW


Before we jump into this exciting class, we need to fully understand how to work with decimals.  As you may recall, percentages are nothing more just numbers behind a decimal.

  • 50% is the same as 0.5
  • 25% is the same as 0.25
  • 1% is the same as 0.01
  • 125% is 1.25
100% is the whole thing. If you eat an entire pie, you eat 100% of the pie. If you eat half the pie, you eat 50% of the it. It’s pretty simple really.

Moving decimals is just as simple. Take 10% of 100 and you get 10. Why? Well, 10% is one decimal place. 1% of 100 is 1, because you moved the decimal place two places over.
