In the realm of mathematics, percentages play a fundamental role in expressing proportions and representing parts of a whole. Understanding how to calculate percentages is crucial for everyday life, from determining discounts at the store to analyzing financial data. One common scenario involves figuring out what number a given percentage represents a part of. For instance, “36 is 60 percent of what number?” This seemingly simple question unlocks a deeper understanding of percentage calculations and their practical applications.
Understanding Percentages
A percentage is a fraction expressed out of one hundred. The symbol “%” represents “out of one hundred.” For example, 60% is equivalent to 60/100, which can be simplified to 0.60. Percentages are widely used to express proportions, ratios, and changes in quantities. They provide a convenient way to compare different values and understand their relative sizes.
Calculating Percentages
To calculate a percentage of a number, follow these steps:
- Convert the percentage to a decimal by dividing it by 100.
- Multiply the decimal by the number.
For example, to find 60% of 50, follow these steps:
- 60% / 100 = 0.60
- 0.60 * 50 = 30
Therefore, 60% of 50 is 30.
Solving the Problem: 36 Is 60 Percent of What Number?
Now, let’s apply our understanding of percentages to solve the problem: “36 is 60 percent of what number?” (See Also: How Do You Use Algebra In Real Life? – Beyond The Classroom)
Setting Up the Equation
We can represent this problem mathematically as follows:
36 = 60% * x
where “x” is the unknown number.
Solving for x
To solve for “x,” follow these steps:
- Convert 60% to a decimal: 60% / 100 = 0.60
- Rewrite the equation: 36 = 0.60 * x
- Divide both sides of the equation by 0.60: 36 / 0.60 = x
- Calculate the result: x = 60
Therefore, 36 is 60 percent of 60. (See Also: Definition of Prime Number in Math? Unlocking The Secrets)
