### Step 2: Multiply the decimal by the number.

The second step is to multiply the decimal, which we got from step one, by the number, which is 36. You can do this using a calculator as follows:

Step one: |
30/100 = 0.3 |

Step two: |
0.3 x 36 = 10.8 |

Therefore, 30% of 36 is 10.8. This means that if you had 36 items and you sold 30% of them, you would have sold 10.8 items.

## Other ways to calculate 30% of 36

In addition to the above method, there are other ways to calculate 30% of 36 as follows:

### Method one: Cross Multiplication

In this method, you can find 30% of 36 by cross-multiplying.

30% of 36 = (30/100) x 36

= (30 x 36) / 100

= 1080 / 100

= 10.8

### Method two: Percentage Formula

The percentage formula can also be used to calculate 30% of 36. The formula is:

Part/Whole x 100 = Percentage

Part refers to the fraction or decimal you want to find, while the whole represents the number.

Therefore, 30% of 36 can be calculated as:

Part/Whole x 100 = Percentage

P/36 x 100 = 30%

P/36 = 30/100

P/36 = 0.3

P = 0.3 x 36

P = 10.8

## Conclusion

Calculating 30% of 36 may seem challenging, but it’s easy once you understand the process. Knowing how to calculate percentages helps you solve a wide range of numerical problems. Whether you’re working with fractions, ratios, or decimals, understanding percentages can help you make better financial decisions.
