# 7 is 20% of What Number?

## Understanding Percentages

Percentages are a way of expressing a fraction of a whole as a number out of 100. They are commonly used in mathematics, finance, and everyday life to compare parts of a whole. The symbol “%” is used to denote percentages.

## Calculating the Whole Number

To find the whole number when a part is given as a percentage, you can use the following formula:

```
Whole Number = Part / Percentage
```

In this case, we are given that 7 is 20% of an unknown number. So, we can plug these values into the formula to solve for the whole number:

```
Whole Number = 7 / 20
```

```
Whole Number = 0.35
```

Therefore, 7 is 20% of 0.35.

## Percentage Proportions

Another way to solve this problem is to use percentage proportions. A percentage proportion is an equation that sets two percentages equal to each other. In this case, we can set up the following proportion:

```
7 / Whole Number = 20 / 100
```

This proportion states that 7 is to the whole number as 20 is to 100. We can cross-multiply to solve for the whole number:

```
7 * 100 = Whole Number * 20
```

```
700 = 20 * Whole Number
```

```
Whole Number = 700 / 20
```

```
Whole Number = 35
```

Therefore, 7 is 20% of 35.

## Conclusion

In conclusion, 7 is 20% of 0.35 or 35. This can be found using the formula `Whole Number = Part / Percentage`

or by setting up a percentage proportion.
