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.
