What is 78.7 percent of 500 - 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 500 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 500 is 100%, so we can write it down as 500=100%.
4. We know, that x is 78.7% of the output value, so we can write it down as x=78.7%.
5. Now we have two simple equations:
1) 500=100%
2) x=78.7%
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:
500/x=100%/78.7%
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 78.7% of 500

500/x=100/78.7
(500/x)*x=(100/78.7)*x       - we multiply both sides of the equation by x
500=1.2706480304956*x       - we divide both sides of the equation by (1.2706480304956) to get x
500/1.2706480304956=x
393.5=x
x=393.5

now we have:
78.7% of 500=393.5
