21 is 12 percent of what?

Answer: 21 is 12 percent of 175. Alternatively, we can say that 175 is the number of which 21 is equivalent to 12%.

Solution for 21 is 12 percent of what:

$21=\mathrm{12\%}ofn$ $21=\frac{12}{100}\times n$ $21\times \frac{100}{12}=n$ $n=21\times \frac{100}{12}$ $n=\frac{21\times 100}{12}$ $n=\frac{2100}{12}$ $n=175$

Now we have that 21 is 12% of 175. Alternatively, we can express it as 175 is the number of which 21 is 12%.

The step-by-step process for finding 21 is 12 percent of what:

The mathematical calculation of 21 is 12% of a number can be broken down as follows:

• 21 = 12% of n
• Convert this into an equation: 21 = (12/100) * n
• Rearrange the equation to solve for n: 21 * (100/12) = n
• Simplify the equation further: n = 21 * (100/12) => (21 * 100)/12
• Carry out the calculation: n = 2100 / 12
• The final answer is: n = 175

Thus, we conclude that 21 is 12 percent of 175.

Explanation for 21 is 12 percent of what:

Step 1: Set up the equation

We start with the equation 21 is 12% of what number (n). This can be written as:

$21=\mathrm{12\%}ofn$

Think of percent as parts out of 100. So, when we say 12 percent, it's like having 12 parts out of a total of 100. What we want to do now is find out what the total would be if 21 was equivalent to 12 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. 12% becomes 12/100. This gives us:

$21=\frac{12}{100}\times n$

This is like saying 21 is 12 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 (100/12):

$n=21\times \frac{100}{12}$

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 21 (our 21 parts) by (100/12) (the reciprocal of our percentage in decimal form).

Step 4: Simplify the equation

This simplifies to:

$n=\frac{21\times 100}{12}$

Step 5: Perform the calculation

Performing the calculation gives us the final answer:

$n=\frac{2100}{12}$ $n=175$

Finally, after dividing 2100 by 12, we arrive at the answer: 175. Hence, we can definitively say that 21 is 12% of 175.

This guide aims to simplify the understanding of percentage calculations, focusing on the question 21 is 12 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.
