What is 51.5 percent of 259 - 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 259 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 259 is 100%, so we can write it down as 259=100%.
4. We know, that x is 51.5% of the output value, so we can write it down as x=51.5%.
5. Now we have two simple equations:
1) 259=100%
2) x=51.5%
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:
259/x=100%/51.5%
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 51.5% of 259

259/x=100/51.5
(259/x)*x=(100/51.5)*x       - we multiply both sides of the equation by x
259=1.9417475728155*x       - we divide both sides of the equation by (1.9417475728155) to get x
259/1.9417475728155=x
133.385=x
x=133.385

now we have:
51.5% of 259=133.385
