Understanding the Problem: The question "150 is what percent of 200?" essentially asks us to find the ratio of 150 to 200 and express that ratio as a percentage.

Step-by-Step Calculation:

1. Set up the Equation: We can represent the problem as a simple equation:

   x% of 200 = 150

   Where 'x' represents the percentage we're trying to find.

2. Convert the Percentage to a Decimal: To solve for 'x', we first need to convert the percentage to a decimal. We do this by dividing the percentage by 100. In this case, we don't know the percentage yet, so we keep it as 'x/100'.

3. Rewrite the Equation: Our equation now becomes:

   (x/100) * 200 = 150

4. Solve for x: To isolate 'x', we follow these steps:

   • Simplify the equation: 2x = 150
   • Divide both sides by 2: x = 75

5. Express as a Percentage: Therefore, x = 75%, meaning 150 is 75% of 200.

Alternative Method: Using a Proportion

Another way to solve this is by setting up a proportion:

150/200 = x/100

Cross-multiplying gives you:

200x = 15000

Dividing both sides by 200 yields:

x = 75

Therefore, again, 150 is 75% of 200.
