Understanding how to calculate percentages is essential in various aspects of life, such as budgeting, financial planning, and problem-solving. By breaking down the process step-by-step, we will provide a clear explanation of how to find 30% of 90.

What does it mean to find 30% of 90?

Before diving into the calculations, let's understand what it means to find 30% of 90. When we talk about finding a percentage of a number, we are essentially looking for a portion or fraction of that number. In this case, we want to determine what 30% of 90 is, which means finding 30% of the total value of 90.

Step 1: Convert the percentage to a decimal

The first step in finding 30% of 90 is to convert the percentage to a decimal. To do this, we divide the percentage value by 100. In this case, 30 divided by 100 equals 0.3. So, 30% can be represented as 0.3 in decimal form.

Step 2: Multiply the decimal by the number

Once we have converted the percentage to a decimal, the next step is to multiply it by the given number. In this case, we multiply 0.3 (the decimal equivalent of 30%) by 90 (the given number).

Calculation:

0.3 * 90 = 27

Step 3: Interpret the result

After performing the multiplication, we find that 0.3 multiplied by 90 equals 27. Therefore, 30% of 90 is equal to 27. This means that if we take 30% of the total value of 90, we will have a result of 27.

Alternative method: Cross-multiplication

An alternative method to find 30% of 90 involves using cross-multiplication. We set up a proportion where the percentage (30) is to the whole (100) as the result (x) is to the given number (90).

Proportion:

30/100 = x/90

Solving the proportion:

To solve the proportion, we can use cross-multiplication. By multiplying the numerator of one fraction by the denominator of the other fraction and vice versa, we obtain:

(30 * 90) = (100 * x)

2700 = 100x

To isolate the variable x, we divide both sides of the equation by 100:

x = 27

Conclusion

In conclusion, finding 30% of 90 requires converting the percentage to a decimal, multiplying it by the given number, and interpreting the result. By following the step-by-step process outlined in this article, we determined that 30% of 90 is equal to 27. Understanding how to calculate percentages allows us to solve various mathematical problems and make informed decisions in our daily lives.
