What is 10 Percent of 129?

What is 10 percent of 129?

Answer: 10 percent of 129 is 12.9. Alternatively, we can say that 12.9 is equivalent to 10% of 129.

Solution for What is 10 percent of 129:

n = 10 percent of 129

n = 10 % * 129

n = \frac{10}{100} * 129

n = \frac{10 * 129}{100}

n = \frac{1290}{100}

n = 12.9

Now we have 10% of 129 = 12.9. Alternatively, we can express it as 10 percent of 129 equals 12.9.

The step-by-step process for finding what is 10 percent of 129:

The mathematical calculation of 10% of 129 can be broken down as follows:

10 percent * 129
Convert this into an equation: (10 / 100) * 129
Simplify the equation further: (10 * 129) / 100
Carry out the calculation: 1290 / 100
The final answer is: 12.9

Thus, we conclude that 10% of 129 is 12.9.

Explanation for What is 10% of 129:

Step 1: **10 percent * 129**

Think of percent as parts out of 100. So, when we say 10 percent, it's like having 10 parts out of a total of 100. What we want to do now is find out what those 10 parts would be if our total was 129 instead of 100.

Step 2: **(10 / 100) * 129**

This is like dividing our 10 parts into 100. It's as if we have 100 pieces of candy and we only want 10 of those pieces. That gives us 0.10 or 10 hundredths. Now we multiply those 10 parts (or 0.10) by 129 to find out what 10% of 129 would be.

Step 3: **(10 * 129) / 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 10 (our 10 parts) by 129 (our total amount), and then we divide that by 100.

Step 4: 1290 / 100

The previous step gave us 1290. 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 129. That's why we divide 1290 by 100.

Step 5: 12.9

Finally, after dividing 1290 by 100, we arrive at the answer: 12.9. Hence, we can definitively say that 10% of 129 equals 12.9.
