Understanding percentage calculations is crucial in various fields, from finance and shopping to data analysis and everyday life. This seemingly simple question allows us to explore the fundamental concepts of percentages and their practical applications. We'll break down the process step-by-step, making it easy to understand and replicate for similar problems.

Understanding the Problem

The question "What percent of 90 is 60?" asks us to find the percentage value that, when applied to 90, results in 60. We can represent this mathematically as:

X% of 90 = 60

Where 'X' represents the unknown percentage we need to find.

Method 1: Using a Proportion

One effective method to solve this involves setting up a proportion. A proportion is an equation stating that two ratios are equal. We can set up the proportion as follows:

X/100 = 60/90

This proportion states that the ratio of the unknown percentage (X) to 100 (the total percentage) is equal to the ratio of 60 to 90.

To solve for X, we can cross-multiply:

90X = 6000

Then, divide both sides by 90:

X = 6000/90 = 66.67 (approximately)

Therefore, 60 is approximately 66.67% of 90.

Method 2: Using a Formula

Another way to solve this is using a straightforward formula:

(Part / Whole) * 100 = Percentage

In our case:

Part = 60 Whole = 90

Substituting these values into the formula:

(60 / 90) * 100 = 66.67%

This confirms our previous result.
