What is 73 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 73% of the output value, so we can write it down as x=73%.
5. Now we have two simple equations:
1) 215=100%
2) x=73%
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%/73%
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 73% of 215

215/x=100/73
(215/x)*x=(100/73)*x       - we multiply both sides of the equation by x
215=1.3698630136986*x       - we divide both sides of the equation by (1.3698630136986) to get x
215/1.3698630136986=x
156.95=x
x=156.95

now we have:
73% of 215=156.95
