What is 21 Percent of 20?

What is 21 percent of 20?

Answer: 21 percent of 20 is 4.2. Alternatively, we can say that 4.2 is equivalent to 21% of 20.

Solution for What is 21 percent of 20:

n = 21 percent of 20

n = 21 % * 20

n = \frac{21}{100} * 20

n = \frac{21 * 20}{100}

n = \frac{420}{100}

n = 4.2

Now we have 21% of 20 = 4.2. Alternatively, we can express it as 21 percent of 20 equals 4.2.

The step-by-step process for finding what is 21 percent of 20:

The mathematical calculation of 21% of 20 can be broken down as follows:

21 percent * 20
Convert this into an equation: (21 / 100) * 20
Simplify the equation further: (21 * 20) / 100
Carry out the calculation: 420 / 100
The final answer is: 4.2

Thus, we conclude that 21% of 20 is 4.2.

Explanation for What is 21% of 20:

Step 1: **21 percent * 20**

Think of percent as parts out of 100. So, when we say 21 percent, it's like having 21 parts out of a total of 100. What we want to do now is find out what those 21 parts would be if our total was 20 instead of 100.

Step 2: **(21 / 100) * 20**

This is like dividing our 21 parts into 100. It's as if we have 100 pieces of candy and we only want 21 of those pieces. That gives us 0.21 or 21 hundredths. Now we multiply those 21 parts (or 0.21) by 20 to find out what 21% of 20 would be.

Step 3: **(21 * 20) / 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 21 (our 21 parts) by 20 (our total amount), and then we divide that by 100.

Step 4: 420 / 100

The previous step gave us 420. 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 20. That's why we divide 420 by 100.

Step 5: 4.2

Finally, after dividing 420 by 100, we arrive at the answer: 4.2. Hence, we can definitively say that 21% of 20 equals 4.2.
