What is 245 percent of 215 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 215 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 215 is 100%, so we can write it down as 215=100%.
4. We know, that x is 245% of the output value, so we can write it down as x=245%.
5. Now we have two simple equations:
1) 215=100%
2) x=245%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
215/x=100%/245%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 245% of 215

215/x=100/245
(215/x)*x=(100/245)*x       - we multiply both sides of the equation by x
215=0.40816326530612*x       - we divide both sides of the equation by (0.40816326530612) to get x
215/0.40816326530612=x
526.75=x
x=526.75

now we have:
245% of 215=526.75
