69.4 is what percent of 170.3 - 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 170.3 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 170.3, so we can write it down as 100%=170.3.
4. We know, that x% equals 69.4 of the output value, so we can write it down as x%=69.4.
5. Now we have two simple equations:
1) 100%=170.3
2) x%=69.4
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%=170.3/69.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 69.4 is what percent of 170.3

100%/x%=170.3/69.4
(100/x)*x=(170.3/69.4)*x       - we multiply both sides of the equation by x
100=2.4538904899135*x       - we divide both sides of the equation by (2.4538904899135) to get x
100/2.4538904899135=x
40.751614797416=x
x=40.751614797416

now we have:
69.4 is 40.751614797416% of 170.3
