# Percentages

#### Getting a percentage of a number

```
10% of 200 | 20
25% × 200  | 50
```

#### Adding a percentage to or taking a percentage off a number

```
200 + 10%   | 220
10% on 200  | 220

200 - 10%   | 180
10% off 200 | 180
```

#### One number as a percentage of/on/off another number

```
20 is 10% of what   | 200
180 is 10% off what | 200
220 is 10% on what  | 200
```

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

```
50 to 75 is what %    | 50%
40 to 90 as %         | 125%

180 is what % off 200 | 10%
180 is what % on 150  | 20%

20 is what % of 200   | 10%
20 as a % of 200      | 10%

20/200 as %           | 10%
20/200 %              | 10%
```

#### Converting numbers and fractions to percentages

Note that 0.5 is 50%, 2 is 200%.

```
0.35 as %      | 35%
2/5 as percent | 40%
```

### 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**

You can convert a decimal or a percentage to a fraction:

```
2/10 as fraction | 1/5
50% as fraction  | 1/2
```

The percentage in any of the [percentage](/syntax-reference/percentages.md) functions can also be replaced with a fraction:

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

## Multipliers

Format a percentage (or fraction) as a multiplier:

```
20/5 as multiplier | 4x
```

The percentage in any of the [percentage](/syntax-reference/percentages.md) functions can also be replaced with a multiplier.

Use "x", "multiple" or "multiplier":

```
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
```

Getting the change from one number to another as a multiplier

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