Understanding Percentages

Before diving into the calculation, let's quickly review what percentages represent. A percentage is a fraction of 100. So, 3.5% means 3.5 out of every 100. To calculate a percentage of a number, we need to convert the percentage into a decimal.

Method 1: Converting to a Decimal

Step 1: Convert the percentage to a decimal.

To convert 3.5% to a decimal, we divide by 100:

3.5% / 100 = 0.035

Step 2: Multiply the decimal by the number.

Now, we multiply the decimal by 300:

0.035 * 300 = 10.5

Therefore, 3.5% of 300 is 10.5

Method 2: Using Fractions

Alternatively, you can solve this using fractions.

Step 1: Convert the percentage to a fraction.

3.5% can be written as 3.5/100. To simplify, we can multiply both the numerator and denominator by 10 to get rid of the decimal: 35/1000. This fraction can be further simplified to 7/200.

Step 2: Multiply the fraction by the number.

Now, we multiply the fraction by 300:

(7/200) * 300 = 2100/200 = 10.5

Again, we find that 3.5% of 300 is 10.5

Practical Applications

Understanding how to calculate percentages is crucial in various real-world scenarios. For example:

• Sales Tax: Calculating the sales tax on a purchase.
• Discounts: Determining the discount amount on sale items.
• Tips: Figuring out how much to tip at a restaurant.
• Finance: Calculating interest earned or paid.

Conclusion

Calculating 3.5% of 300 is straightforward using either the decimal or fraction method. Both methods yield the same result: 10.5. Mastering this simple calculation will provide a solid foundation for tackling more complex percentage problems in your daily life and various professional fields. Remember to always convert the percentage to a decimal or fraction before performing the multiplication. Now you can confidently calculate percentages in a variety of situations!
