Understanding the Problem

To decrease 240 g by 25%, we need to find 25% of 240 g and subtract it from the original value. Understanding percentages is crucial in this problem, as it will help us calculate the required value.

Calculating 25% of 240 g

To find 25% of 240 g, we need to multiply 240 g by 0.25. Multiplication is a basic arithmetic operation that involves finding the product of two numbers. In this case, we are multiplying 240 g by 0.25.

25\% \text{ of } 240 \text{ g} = 0.25 \times 240 \text{ g}

Performing the Calculation

Now, let's perform the calculation to find 25% of 240 g.

0.25 \times 240 \text{ g} = 60 \text{ g}

Subtracting 25% from the Original Value

Now that we have found 25% of 240 g, we can subtract it from the original value to find the decreased value.

240 \text{ g} - 60 \text{ g} = 180 \text{ g}

Conclusion

Therefore, decreasing 240 g by 25% results in 180 g.

Understanding the Problem

In our previous article, we discussed how to decrease 240 g by 25%. In this article, we will answer some frequently asked questions related to the problem.

Q: What is the formula to decrease a value by a percentage?

A: The formula to decrease a value by a percentage is:

\text{Decreased value} = \text{Original value} - (\text{Percentage} \times \text{Original value})

Q: How do I calculate 25% of a value?

A: To calculate 25% of a value, you need to multiply the value by 0.25.

25\% \text{ of } \text{value} = 0.25 \times \text{value}

Q: What is the difference between decreasing a value by a percentage and increasing a value by a percentage?

A: Decreasing a value by a percentage involves subtracting a percentage of the original value from the original value, while increasing a value by a percentage involves adding a percentage of the original value to the original value.

Q: Can I use a calculator to calculate percentages?

A: Yes, you can use a calculator to calculate percentages. In fact, using a calculator can help you avoid errors and make the calculation process easier.

Q: What are some common mistakes to avoid when calculating percentages?
