What is 75 percent of 21?

Answer: 75 percent of 21 is 15.75. Alternatively, we can say that 15.75 is equivalent to 75% of 21.

Solution for What is 75 percent of 21:

n = 75 percent of 21

n = 75 % * 21

n = \frac{75}{100} * 21

n = \frac{75 * 21}{100}

n = \frac{1575}{100}

n = 15.75

Now we have 75% of 21 = 15.75. Alternatively, we can express it as 75 percent of 21 equals 15.75.

The step-by-step process for finding what is 75 percent of 21:

The mathematical calculation of 75% of 21 can be broken down as follows:

75 percent * 21
Convert this into an equation: (75 / 100) * 21
Simplify the equation further: (75 * 21) / 100
Carry out the calculation: 1575 / 100
The final answer is: 15.75

Thus, we conclude that 75% of 21 is 15.75.

Explanation for What is 75% of 21:

Step 1: **75 percent * 21**

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 those 75 parts would be if our total was 21 instead of 100.

Step 2: **(75 / 100) * 21**

This is like dividing our 75 parts into 100. It's as if we have 100 pieces of candy and we only want 75 of those pieces. That gives us 0.75 or 75 hundredths. Now we multiply those 75 parts (or 0.75) by 21 to find out what 75% of 21 would be.

Step 3: **(75 * 21) / 100**

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 75 (our 75 parts) by 21 (our total amount), and then we divide that by 100.

Step 4: 1575 / 100

The previous step gave us 1575. But remember we were pretending our total was 100? Now we have to divide by 100 to get back to the number for our real total, which is 21. That's why we divide 1575 by 100.

Step 5: 15.75

Finally, after dividing 1575 by 100, we arrive at the answer: 15.75. Hence, we can definitively say that 75% of 21 equals 15.75.
