299 is what percent of 510 - 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 510 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 100% equals 510, so we can write it down as 100%=510.
4. We know, that x% equals 299 of the output value, so we can write it down as x%=299.
5. Now we have two simple equations:
1) 100%=510
2) x%=299
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:
100%/x%=510/299
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 299 is what percent of 510

100%/x%=510/299
(100/x)*x=(510/299)*x       - we multiply both sides of the equation by x
100=1.7056856187291*x       - we divide both sides of the equation by (1.7056856187291) to get x
100/1.7056856187291=x
58.627450980392=x
x=58.627450980392

now we have:
299 is 58.627450980392% of 510
