Understanding the Problem: "What Percent of 35 is 7?"

The question "What percent of 35 is 7?" is asking us to find the percentage representing the ratio of 7 to 35. In simpler terms, we need to determine what fraction of 35 is equivalent to 7, and then express that fraction as a percentage.

Method 1: Using a Proportion

This method is great for visualizing the relationship between the numbers. We set up a proportion:

Part/Whole = Percent/100

In our case:

7/35 = x/100

Here, 'x' represents the unknown percentage we're trying to find. To solve for x, we cross-multiply:

7 * 100 = 35 * x
700 = 35x

Now, divide both sides by 35:

x = 700 / 35
x = 20

Therefore, 7 is 20% of 35.

Method 2: Using Decimal Conversion

This method is quicker once you understand the concept. We first express the ratio of 7 to 35 as a decimal:

7 / 35 = 0.2

To convert this decimal to a percentage, we multiply by 100:

0.2 * 100 = 20

Again, we find that 7 is 20% of 35.

Method 3: Using a Calculator

Most calculators have a percentage function. You can simply input "7 ÷ 35 * 100" to directly obtain the answer: 20%.

Practical Applications

Understanding percentage calculations is essential in various situations, including:

Discounts: Calculating savings on sale items.
