Understanding the Problem:

The question "What percent of 200 is 40?" essentially asks us to find the percentage that represents 40 out of 200. To solve this, we need to use a simple formula.

The Formula:

The basic formula for calculating percentages is:

(Part / Whole) * 100% = Percentage

In our case:

• Part: 40 (the value we're interested in)
• Whole: 200 (the total value)

Step-by-Step Calculation:

1. Divide the part by the whole: 40 / 200 = 0.2

2. Multiply the result by 100%: 0.2 * 100% = 20%

Therefore, 40 is 20% of 200.

Alternative Method: Using Proportions

You can also solve this using proportions. We can set up a proportion:

40/200 = x/100

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

200x = 4000

x = 4000 / 200

x = 20

Therefore, again, x = 20%.

Practical Applications:
