42.99 is what percent of 169.99 - 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 169.99 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 169.99, so we can write it down as 100%=169.99.
4. We know, that x% equals 42.99 of the output value, so we can write it down as x%=42.99.
5. Now we have two simple equations:
1) 100%=169.99
2) x%=42.99
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%=169.99/42.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.99 is what percent of 169.99

100%/x%=169.99/42.99
(100/x)*x=(169.99/42.99)*x       - we multiply both sides of the equation by x
100=3.9541753896255*x       - we divide both sides of the equation by (3.9541753896255) to get x
100/3.9541753896255=x
25.289722924878=x
x=25.289722924878

now we have:
