What is 0.3 Percent of 21?

What is 0.3 percent of 21?

Answer: 0.3 percent of 21 is 0.063. Alternatively, we can say that 0.063 is equivalent to 0.3% of 21.

Solution for What is 0.3 percent of 21:

n = 0.3 percent of 21

n = 0.3 % * 21

n = \frac{0.3}{100} * 21

n = \frac{0.3 * 21}{100}

n = \frac{6.3}{100}

n = 0.063

Now we have 0.3% of 21 = 0.063. Alternatively, we can express it as 0.3 percent of 21 equals 0.063.

The step-by-step process for finding what is 0.3 percent of 21:

The mathematical calculation of 0.3% of 21 can be broken down as follows:

0.3 percent * 21
Convert this into an equation: (0.3 / 100) * 21
Simplify the equation further: (0.3 * 21) / 100
Carry out the calculation: 6.3 / 100
The final answer is: 0.063

Thus, we conclude that 0.3% of 21 is 0.063.

Explanation for What is 0.3% of 21:

Step 1: **0.3 percent * 21**

Think of percent as parts out of 100. So, when we say 0.3 percent, it's like having 0.3 parts out of a total of 100. What we want to do now is find out what those 0.3 parts would be if our total was 21 instead of 100.

Step 2: **(0.3 / 100) * 21**

This is like dividing our 0.3 parts into 100. It's as if we have 100 pieces of candy and we only want 0.3 of those pieces. That gives us 0.0.3 or 0.3 hundredths. Now we multiply those 0.3 parts (or 0.0.3) by 21 to find out what 0.3% of 21 would be.

Step 3: **(0.3 * 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 0.3 (our 0.3 parts) by 21 (our total amount), and then we divide that by 100.

Step 4: 6.3 / 100

The previous step gave us 6.3. 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 6.3 by 100.

Step 5: 0.063

Finally, after dividing 6.3 by 100, we arrive at the answer: 0.063. Hence, we can definitively say that 0.3% of 21 equals 0.063.
