The first thing to remember: «nine percent of ten thousand» it's written as «9% of 10000». The symbol «%» is often used to make the mathematical expression shorter.
When they talk about 9% of something, they mean that we need to take 9 fragments of the something Whole. One percent means part per one hundred all the time. And we must remember the rule: «The sum of all parts of the whole is 100%». In fact, you have to divide 10000 into 100 fragments and take 9 of them. Let's try to figure it out together. You can find out how much 9% of 10000 in several ways.
This site below shows some of these methods and an illustration that will help visualize 9% of 10000. By the way, people who learn how to calculate 9% of 10000 will be able to do the same with other numbers later. Explore that we have presented for you and get a complete understanding of the topic of interest.
As a bonus to the lesson at the end you will know what is not equal to 9% and learn how to solve this problem too.
Memorizing the formula for calculating percents is the easiest way to solve the problem "What is 9% of 10000?”. That's why this method is taught in mathematics lessons of schools, because you do not need to know anything about fractional numbers or proportions. Learning the formula will be enough for calculating. The main thing is to correctly determine its components.
The general formula for calculating percentages looks like that:
There are 10000 is the Whole, and 9 is the Percent, but the X is the desired result.
So, you can to get an answer to the question «What is nine percent of ten thousand»:
Now you know that 9% of 10000 it is equal to nine hundreds!
If you know how to deal with decimal numbers, then you can use another method. You may to convert the percent as a decimal number. It is easy. You can do this by dividing 9 by 100. Just move the decimal point 2 places to the left. So, 9% in decimal form is equal to 0.09
And next just multiply the resulting decimal number with a Whole (with 10000):
You get 900 again! So, we can use equivalent forms of percentages interchangeably and choose the one(s) that best suit our purpose.
It is a good method which can show you what is 9 percent of 10000. Recall that 10000 is a Whole, and a Whole is 100 Parts.
Let's make an equation from this proportion to calculate the Part. We need to multiply the numbers cross by cross:
Let's solve this equation and find the unknown:
So, 9% of 10000 it is 900 again.
Look at the diagram we have drawn for you. It shows 9% of the Whole. The pie chart has 10000 fragments, and the blue fragment of the circle is 900, or 9% of 10000.
Interestingly, the diagram of 9% from any integer will look the same. Because it is always 9 parts of 100 something. Although the answer to the problem will be different, the picture will be the same. For example, 9% of 100 would be 9, which is 9 parts of 100 parts. And the blue part will always take up 9 percent of the circle, because it's always 9 parts of 100.
Since you know the sum is 100%, so to calculate «What is not equal to 9%» you can subtract 9% from 100%. The next step is to take that percents from 10000 (we used the formula again):
Or just subtract 900 from 10000:
The lesson is over. We hope that we have shown everything clearly enough for you to become a real expert.
