What is 30 percent of 400?

Answer: 30 percent of 400 is 120. Alternatively, we can say that 120 is equivalent to 30% of 400.

Solution for What is 30 percent of 400:

n = 30 percent of 400 n = 30 % 400 n = 30 100 400 n = 30 400 100 n = 12000 100 n = 120

Now we have 30% of 400 = 120. Alternatively, we can express it as 30 percent of 400 equals 120.


The step-by-step process for finding what is 30 percent of 400:

The mathematical calculation of 30% of 400 can be broken down as follows:

  • 30 percent * 400
  • Convert this into an equation: (30 / 100) * 400
  • Simplify the equation further: (30 * 400) / 100
  • Carry out the calculation: 12000 / 100
  • The final answer is: 120

Thus, we conclude that 30% of 400 is 120.


Explanation for What is 30% of 400:

Step 1: 30 percent * 400

Think of percent as parts out of 100. So, when we say 30 percent, it's like having 30 parts out of a total of 100. What we want to do now is find out what those 30 parts would be if our total was 400 instead of 100.

Step 2: (30 / 100) * 400

This is like dividing our 30 parts into 100. It's as if we have 100 pieces of candy and we only want 30 of those pieces. That gives us 0.30 or 30 hundredths. Now we multiply those 30 parts (or 0.30) by 400 to find out what 30% of 400 would be.

Step 3: (30 * 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 30 (our 30 parts) by 400 (our total amount), and then we divide that by 100.

Step 4: 12000 / 100

The previous step gave us 12000. 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 12000 by 100.

Step 5: 120

Finally, after dividing 12000 by 100, we arrive at the answer: 120. Hence, we can definitively say that 30% of 400 equals 120.
