What is 20 percent of 529.9 - 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 529.9 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 529.9 is 100%, so we can write it down as 529.9=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 529.9=100%
2) x=20%
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:
529.9/x=100%/20%
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 20% of 529.9

529.9/x=100/20
(529.9/x)*x=(100/20)*x       - we multiply both sides of the equation by x
529.9=5*x       - we divide both sides of the equation by (5) to get x
529.9/5=x
105.98=x
x=105.98

now we have:
20% of 529.9=105.98
