234.5 is what percent of 670 - 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 670 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 670, so we can write it down as 100%=670.
4. We know, that x% equals 234.5 of the output value, so we can write it down as x%=234.5.
5. Now we have two simple equations:
1) 100%=670
2) x%=234.5
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%=670/234.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 234.5 is what percent of 670

100%/x%=670/234.5
(100/x)*x=(670/234.5)*x       - we multiply both sides of the equation by x
100=2.85714285714*x       - we divide both sides of the equation by (2.85714285714) to get x
100/2.85714285714=x
35=x
x=35

now we have:
234.5 is 35% of 670
