9 is 80 percent of what?

Answer: 9 is 80 percent of 11.25. Alternatively, we can say that 11.25 is the number of which 9 is equivalent to 80%.

Solution for 9 is 80 percent of what:

9 = 80% of n 9 = 80 100 × n 9 × 100 80 = n n = 9 × 100 80 n = 9 × 100 80 n = 900 80 n = 11.25

Now we have that 9 is 80% of 11.25. Alternatively, we can express it as 11.25 is the number of which 9 is 80%.


The step-by-step process for finding 9 is 80 percent of what:

The mathematical calculation of 9 is 80% of a number can be broken down as follows:

  • 9 = 80% of n
  • Convert this into an equation: 9 = (80/100) * n
  • Rearrange the equation to solve for n: 9 * (100/80) = n
  • Simplify the equation further: n = 9 * (100/80) => (9 * 100)/80
  • Carry out the calculation: n = 900 / 80
  • The final answer is: n = 11.25

Thus, we conclude that 9 is 80 percent of 11.25.


Explanation for 9 is 80 percent of what:

Step 1: Set up the equation

We start with the equation 9 is 80% of what number (n). This can be written as:

9 = 80% of n

Think of percent as parts out of 100. So, when we say 80 percent, it's like having 80 parts out of a total of 100. What we want to do now is find out what the total would be if 9 was equivalent to 80 parts instead of 100.

Step 2: Convert the percentage to a fraction and set up the equation

Next, we convert the percentage to a fraction and set up the equation. 80% becomes 80/100. This gives us:

9 = 80 100 × n

This is like saying 9 is 80 parts (out of 100) of a total (n). We want to find out what that total (n) is.

Step 3: Rearrange the equation to solve for n

To solve for n, we need to get n on one side of the equation by itself. We can do this by multiplying both sides of the equation by (100/80):

n = 9 × 100 80

This is an alternative calculation. Instead of doing it in two steps like we did before, we can also do it in one step. First, we multiply 9 (our 9 parts) by (100/80) (the reciprocal of our percentage in decimal form).

Step 4: Simplify the equation

This simplifies to:

n = 9 × 100 80

Step 5: Perform the calculation

Performing the calculation gives us the final answer:

n = 900 80 n = 11.25

Finally, after dividing 900 by 80, we arrive at the answer: 11.25. Hence, we can definitively say that 9 is 80% of 11.25.

This guide aims to simplify the understanding of percentage calculations, focusing on the question 9 is 80 percent of what. Keep practicing with different numbers to hone your skills in percentage calculations. We hope this helps you in your quest for better mathematical understanding.
