What is 15 percent of 90?

Answer: 15 percent of 90 is 13.5. Alternatively, we can say that 13.5 is equivalent to 15% of 90.

Solution for What is 15 percent of 90:

n = 15 percent of 90 n = 15 % 90 n = 15 100 90 n = 15 90 100 n = 1350 100 n = 13.5

Now we have 15% of 90 = 13.5. Alternatively, we can express it as 15 percent of 90 equals 13.5.


The step-by-step process for finding what is 15 percent of 90:

The mathematical calculation of 15% of 90 can be broken down as follows:

  • 15 percent * 90
  • Convert this into an equation: (15 / 100) * 90
  • Simplify the equation further: (15 * 90) / 100
  • Carry out the calculation: 1350 / 100
  • The final answer is: 13.5

Thus, we conclude that 15% of 90 is 13.5.


Explanation for What is 15% of 90:

Step 1: 15 percent * 90

Think of percent as parts out of 100. So, when we say 15 percent, it's like having 15 parts out of a total of 100. What we want to do now is find out what those 15 parts would be if our total was 90 instead of 100.

Step 2: (15 / 100) * 90

This is like dividing our 15 parts into 100. It's as if we have 100 pieces of candy and we only want 15 of those pieces. That gives us 0.15 or 15 hundredths. Now we multiply those 15 parts (or 0.15) by 90 to find out what 15% of 90 would be.

Step 3: (15 * 90) / 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 15 (our 15 parts) by 90 (our total amount), and then we divide that by 100.

Step 4: 1350 / 100

The previous step gave us 1350. 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 90. That's why we divide 1350 by 100.

Step 5: 13.5

Finally, after dividing 1350 by 100, we arrive at the answer: 13.5. Hence, we can definitively say that 15% of 90 equals 13.5.
