 Convert the following fraction to a percentage and decimal:  → 30 20

This is also written as 30 is what percent of 20?

 Percentage  = Numerator * 100 Denominator

Evaluating using our inputs, we get:
 Percentage  = 30 * 100 20

 Percentage  = 3000 20

Percentage  =   150%

Now we need to calculate the decimal version of the percentage:
The decimal version of a percentage is just the percentage divided by 100.

Dividing by 100 is the same as shifting the decimal point 2 places to the left.
Shifting 150 one decimal place to the left, we get --> 15
Shifting 15 another decimal place to the left, we get --> 1.5

## Check to see if 1.5 is a terminating decimal:

A terminating decimal is one that ends and does not repeat
Since the decimals 5 does not repeat, this is a terminating decimal

### How does the Percentage-Decimal-Fraction Relations Calculator work?
