The first thing to remember: «thirteen percent of eighty five thousand» it's written as «13% of 85000». The symbol «%» is often used to make the mathematical expression shorter.
When they talk about 13% of something, they mean that we need to take 13 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 85000 into 100 fragments and take 13 of them. Let's try to figure it out together. You can find out how much 13% of 85000 in several ways.
This site below shows some of these methods and an illustration that will help visualize 13% of 85000. By the way, people who learn how to calculate 13% of 85000 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 13% and learn how to solve this problem too.
Memorizing the formula for calculating percents is the easiest way to solve the problem "What is 13% of 85000?”. 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 85000 is the Whole, and 13 is the Percent, but the X is the desired result.
So, you can to get an answer to the question «What is thirteen percent of eighty five thousand»:
Now you know that 13% of 85000 it is equal to eleven thousand and fifty!
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 13 by 100. Just move the decimal point 2 places to the left. So, 13% in decimal form is equal to 0.13
And next just multiply the resulting decimal number with a Whole (with 85000):
You get 11050 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 13 percent of 85000. Recall that 85000 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, 13% of 85000 it is 11050 again.
Look at the diagram we have drawn for you. It shows 13% of the Whole. The pie chart has 85000 fragments, and the blue fragment of the circle is 11050, or 13% of 85000.
Interestingly, the diagram of 13% from any integer will look the same. Because it is always 13 parts of 100 something. Although the answer to the problem will be different, the picture will be the same. For example, 13% of 100 would be 13, which is 13 parts of 100 parts. And the blue part will always take up 13 percent of the circle, because it's always 13 parts of 100.
Since you know the sum is 100%, so to calculate «What is not equal to 13%» you can subtract 13% from 100%. The next step is to take that percents from 85000 (we used the formula again):
Or just subtract 11050 from 85000:
The lesson is over. We hope that we have shown everything clearly enough for you to become a real expert.
