15 is 75 percent of what?
Answer: 15 is 75 percent of 20. Alternatively, we can say that 20 is the number of which 15 is equivalent to 75%.
Solution for 15 is 75 percent of what:
Now we have that 15 is 75% of 20. Alternatively, we can express it as 20 is the number of which 15 is 75%.
The step-by-step process for finding 15 is 75 percent of what:
The mathematical calculation of 15 is 75% of a number can be broken down as follows:
- 15 = 75% of n
- Convert this into an equation: 15 = (75/100) * n
- Rearrange the equation to solve for n: 15 * (100/75) = n
- Simplify the equation further: n = 15 * (100/75) => (15 * 100)/75
- Carry out the calculation: n = 1500 / 75
- The final answer is: n = 20
Thus, we conclude that 15 is 75 percent of 20.
Explanation for 15 is 75 percent of what:
Step 1: Set up the equation
We start with the equation 15 is 75% of what number (n). This can be written as:
Think of percent as parts out of 100. So, when we say 75 percent, it's like having 75 parts out of a total of 100. What we want to do now is find out what the total would be if 15 was equivalent to 75 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. 75% becomes 75/100. This gives us:
This is like saying 15 is 75 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 (100/75):
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 15 (our 15 parts) by (100/75) (the reciprocal of our percentage in decimal form).
Step 4: Simplify the equation
This simplifies to:
Step 5: Perform the calculation
Performing the calculation gives us the final answer:
Finally, after dividing 1500 by 75, we arrive at the answer: 20. Hence, we can definitively say that 15 is 75% of 20.
