What is 72 percent of 670 - 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 670 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 670 is 100%, so we can write it down as 670=100%.
4. We know, that x is 72% of the output value, so we can write it down as x=72%.
5. Now we have two simple equations:
1) 670=100%
2) x=72%
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:
670/x=100%/72%
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 72% of 670

670/x=100/72
(670/x)*x=(100/72)*x       - we multiply both sides of the equation by x
670=1.3888888888889*x       - we divide both sides of the equation by (1.3888888888889) to get x
670/1.3888888888889=x
482.4=x
x=482.4

now we have:
72% of 670=482.4
