291.5 is what percent of 435 - 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 435 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 435, so we can write it down as 100%=435.
4. We know, that x% equals 291.5 of the output value, so we can write it down as x%=291.5.
5. Now we have two simple equations:
1) 100%=435
2) x%=291.5
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:
100%/x%=435/291.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 291.5 is what percent of 435

100%/x%=435/291.5
(100/x)*x=(435/291.5)*x       - we multiply both sides of the equation by x
100=1.4922813036021*x       - we divide both sides of the equation by (1.4922813036021) to get x
100/1.4922813036021=x
67.011494252874=x
x=67.011494252874

now we have:
291.5 is 67.011494252874% of 435
