729.98 is what percent of 429.4 - 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 429.4 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 429.4, so we can write it down as 100%=429.4.
4. We know, that x% equals 729.98 of the output value, so we can write it down as x%=729.98.
5. Now we have two simple equations:
1) 100%=429.4
2) x%=729.98
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%=429.4/729.98
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 729.98 is what percent of 429.4

100%/x%=429.4/729.98
(100/x)*x=(429.4/729.98)*x       - we multiply both sides of the equation by x
100=0.58823529411765*x       - we divide both sides of the equation by (0.58823529411765) to get x
100/0.58823529411765=x
170=x
x=170

now we have:
729.98 is 170% of 429.4
