What is 18 Percent of 40?

What is 18 percent of 40?

Answer: 18 percent of 40 is 7.2. Alternatively, we can say that 7.2 is equivalent to 18% of 40.

Solution for What is 18 percent of 40:

n = 18 percent of 40

n = 18 % * 40

n = \frac{18}{100} * 40

n = \frac{18 * 40}{100}

n = \frac{720}{100}

n = 7.2

Now we have 18% of 40 = 7.2. Alternatively, we can express it as 18 percent of 40 equals 7.2.

The step-by-step process for finding what is 18 percent of 40:

The mathematical calculation of 18% of 40 can be broken down as follows:

18 percent * 40
Convert this into an equation: (18 / 100) * 40
Simplify the equation further: (18 * 40) / 100
Carry out the calculation: 720 / 100
The final answer is: 7.2

Thus, we conclude that 18% of 40 is 7.2.

Explanation for What is 18% of 40:

Step 1: **18 percent * 40**

Think of percent as parts out of 100. So, when we say 18 percent, it's like having 18 parts out of a total of 100. What we want to do now is find out what those 18 parts would be if our total was 40 instead of 100.

Step 2: **(18 / 100) * 40**

This is like dividing our 18 parts into 100. It's as if we have 100 pieces of candy and we only want 18 of those pieces. That gives us 0.18 or 18 hundredths. Now we multiply those 18 parts (or 0.18) by 40 to find out what 18% of 40 would be.

Step 3: **(18 * 40) / 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 18 (our 18 parts) by 40 (our total amount), and then we divide that by 100.

Step 4: 720 / 100

The previous step gave us 720. 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 40. That's why we divide 720 by 100.

Step 5: 7.2

Finally, after dividing 720 by 100, we arrive at the answer: 7.2. Hence, we can definitively say that 18% of 40 equals 7.2.
