10 Is 25 Percent of What Number?

If you have come across the question “10 is 25 percent of what number?”, you might find yourself scratching your head for a moment. This type of problem is commonly encountered in mathematics and requires a bit of logical thinking to solve. In this article, we will break down the steps to find the unknown number and provide some frequently asked questions to help you understand the concept better.

To solve the problem, we need to determine the number that corresponds to 25 percent of 10. Here’s how you can do it:

Step 1: Understand the concept of percent
Before we delve into the problem, it’s crucial to grasp the concept of percent. Percentages are a way of expressing a fraction of a whole, where 100 percent represents the entire quantity. For instance, 25 percent is equivalent to 25/100 or 0.25 as a decimal.

Step 2: Set up the equation
To find the unknown number, let’s represent it as ‘x’. Now, we can set up the equation: 0.25x = 10. This equation states that 25 percent of ‘x’ is equal to 10.

Step 3: Solve the equation
To solve for ‘x’, we need to isolate it on one side of the equation. In this case, we can do this by dividing both sides by 0.25: x = 10 ÷ 0.25. Simplifying the equation gives us: x = 40.

To ensure the accuracy of our solution, we can substitute the found value of ‘x’ back into the original equation: 0.25(40) = 10. Indeed, 10 is indeed 25 percent of 40, confirming that our answer is correct.
