What is 90 Percent of 45?

What is 90 percent of 45?

Answer: 90 percent of 45 is 40.5. Alternatively, we can say that 40.5 is equivalent to 90% of 45.

Solution for What is 90 percent of 45:

n = 90 percent of 45

n = 90 % * 45

n = \frac{90}{100} * 45

n = \frac{90 * 45}{100}

n = \frac{4050}{100}

n = 40.5

Now we have 90% of 45 = 40.5. Alternatively, we can express it as 90 percent of 45 equals 40.5.

The step-by-step process for finding what is 90 percent of 45:

The mathematical calculation of 90% of 45 can be broken down as follows:

90 percent * 45
Convert this into an equation: (90 / 100) * 45
Simplify the equation further: (90 * 45) / 100
Carry out the calculation: 4050 / 100
The final answer is: 40.5

Thus, we conclude that 90% of 45 is 40.5.

Explanation for What is 90% of 45:

Step 1: **90 percent * 45**

Think of percent as parts out of 100. So, when we say 90 percent, it's like having 90 parts out of a total of 100. What we want to do now is find out what those 90 parts would be if our total was 45 instead of 100.

Step 2: **(90 / 100) * 45**

This is like dividing our 90 parts into 100. It's as if we have 100 pieces of candy and we only want 90 of those pieces. That gives us 0.90 or 90 hundredths. Now we multiply those 90 parts (or 0.90) by 45 to find out what 90% of 45 would be.

Step 3: **(90 * 45) / 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 90 (our 90 parts) by 45 (our total amount), and then we divide that by 100.

Step 4: 4050 / 100

The previous step gave us 4050. 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 45. That's why we divide 4050 by 100.

Step 5: 40.5

Finally, after dividing 4050 by 100, we arrive at the answer: 40.5. Hence, we can definitively say that 90% of 45 equals 40.5.
