What is 35 percent of 509990 - 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 509990 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 509990 is 100%, so we can write it down as 509990=100%.
4. We know, that x is 35% of the output value, so we can write it down as x=35%.
5. Now we have two simple equations:
1) 509990=100%
2) x=35%
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:
509990/x=100%/35%
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 35% of 509990

509990/x=100/35
(509990/x)*x=(100/35)*x       - we multiply both sides of the equation by x
509990=2.8571428571429*x       - we divide both sides of the equation by (2.8571428571429) to get x
509990/2.8571428571429=x
178496.5=x
x=178496.5

now we have:
