#### Getting the change from one number to another, as a percent

### Calculations with mixed percentages & decimals

You can do calculations with pure percentages:

10% + 20%                                 | 30%
90% − 40%                                 | 50%

And you can add/subtract decimals & fractions to/from percentages. 1.0 is equivalent to 100%.

30% + 0.4                                 | 70%
100% - 1/2                                | 50%
100% + 2 + 30%                            | 330%

Note that when multiplying a percentage by a number, the answer will always be a number (not a percentage), regardless of order:

50% × 30                                  | 15
30 × 50%                                  | 15

### Fractions and Multipliers

The percentage in any of the aforementioned functions can also be replaced with a fraction:

2/3 of 600                       | 400
50 is 1/5 of what                | 250

You can also use "x", "multiple" or "multiplier" instead of percentage:

50 as x of 5                | 10x
2 as multiplier of 1        | 2x
2 as multiplier on 1        | 1x
1 as x off 2                | 0.5x

Multiplier change from one number to another

50 to 75 is what x                       | 1.5x
20 to 40 as x                            | 2x
