What is 80 Percent of 90?

What is 80 percent of 90?

Answer: 80 percent of 90 is 72. Alternatively, we can say that 72 is equivalent to 80% of 90.

Solution for What is 80 percent of 90:

n = 80 percent of 90

n = 80 % * 90

n = \frac{80}{100} * 90

n = \frac{80 * 90}{100}

n = \frac{7200}{100}

n = 72

Now we have 80% of 90 = 72. Alternatively, we can express it as 80 percent of 90 equals 72.

The step-by-step process for finding what is 80 percent of 90:

The mathematical calculation of 80% of 90 can be broken down as follows:

80 percent * 90
Convert this into an equation: (80 / 100) * 90
Simplify the equation further: (80 * 90) / 100
Carry out the calculation: 7200 / 100
The final answer is: 72

Thus, we conclude that 80% of 90 is 72.

Explanation for What is 80% of 90:

Step 1: **80 percent * 90**

Think of percent as parts out of 100. So, when we say 80 percent, it's like having 80 parts out of a total of 100. What we want to do now is find out what those 80 parts would be if our total was 90 instead of 100.

Step 2: **(80 / 100) * 90**

This is like dividing our 80 parts into 100. It's as if we have 100 pieces of candy and we only want 80 of those pieces. That gives us 0.80 or 80 hundredths. Now we multiply those 80 parts (or 0.80) by 90 to find out what 80% of 90 would be.

Step 3: **(80 * 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 80 (our 80 parts) by 90 (our total amount), and then we divide that by 100.

Step 4: 7200 / 100

The previous step gave us 7200. 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 7200 by 100.

Step 5: 72

Finally, after dividing 7200 by 100, we arrive at the answer: 72. Hence, we can definitively say that 80% of 90 equals 72.
