What is 10 Percent of 400?

What is 10 percent of 400?

Answer: 10 percent of 400 is 40. Alternatively, we can say that 40 is equivalent to 10% of 400.

Solution for What is 10 percent of 400:

n = 10 percent of 400

n = 10 % * 400

n = \frac{10}{100} * 400

n = \frac{10 * 400}{100}

n = \frac{4000}{100}

n = 40

Now we have 10% of 400 = 40. Alternatively, we can express it as 10 percent of 400 equals 40.

The step-by-step process for finding what is 10 percent of 400:

The mathematical calculation of 10% of 400 can be broken down as follows:

10 percent * 400
Convert this into an equation: (10 / 100) * 400
Simplify the equation further: (10 * 400) / 100
Carry out the calculation: 4000 / 100
The final answer is: 40

Thus, we conclude that 10% of 400 is 40.

Explanation for What is 10% of 400:

Step 1: **10 percent * 400**

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 400 instead of 100.

Step 2: **(10 / 100) * 400**

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 400 to find out what 10% of 400 would be.

Step 3: **(10 * 400) / 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 400 (our total amount), and then we divide that by 100.

Step 4: 4000 / 100

The previous step gave us 4000. 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 400. That's why we divide 4000 by 100.

Step 5: 40

Finally, after dividing 4000 by 100, we arrive at the answer: 40. Hence, we can definitively say that 10% of 400 equals 40.
