5 Simple Steps To Find What Percentage Of 120 Is 20

Understanding percentages can often seem challenging, but breaking down the process into simple steps makes it much more manageable. In this article, we will dive into how to find what percentage 20 is of 120 using an easy-to-follow approach.

Why Knowing Percentages is Important? 🤔

Percentages are everywhere—from discounts while shopping to calculating grades in school. Knowing how to calculate percentages not only enhances your mathematical skills but can also aid in making informed decisions in daily life.

Step 1: Write the Formula

To determine what percentage one number (in this case, 20) is of another number (120), we utilize the following formula:

[ \text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100 ]

For our specific example, the Part is 20, and the Whole is 120.

Step 2: Substitute the Values

Now, substitute the values into the formula. It looks like this:

[ \text{Percentage} = \left(\frac{20}{120}\right) \times 100 ]

Step 3: Perform the Division

Next, we need to divide 20 by 120. When you calculate this, you get:

[ \frac{20}{120} = 0.1667 ]

Step 4: Multiply by 100

Now, take the result from the division and multiply it by 100 to convert it into a percentage:

[ 0.1667 \times 100 = 16.67 ]

Step 5: Finalize Your Answer

So, 20 is approximately 16.67% of 120. 🎉 This simple calculation shows you how you can easily find out what percentage one number is of another!

Tips and Tricks for Percentage Calculations

Here are some helpful tips to make your percentage calculations smoother:

• Use a Calculator: For larger numbers, using a calculator can save time and help avoid mistakes.
• Convert to Decimal First: If you find fractions difficult, you can convert them to decimals before multiplying.
• Double-check Your Work: It’s always good practice to verify your calculations by doing the opposite check—take your percentage and find the original number.

Common Mistakes to Avoid

• Misplacing the Decimal: When multiplying by 100, ensure you correctly place the decimal point.
• Ignoring Order of Operations: Remember to perform division before multiplication according to mathematical rules.
• Forgetting to Multiply by 100: A common oversight is forgetting to convert the decimal back into a percentage by multiplying by 100.

Troubleshooting Percentage Problems

If you’re having trouble with percentages, consider the following common issues:

• Misunderstanding Parts and Wholes: Make sure you identify correctly which number is the part and which is the whole.
• Calculator Errors: Ensure you’re entering the numbers correctly into your calculator to avoid mistakes.
