0.15 is what percent of 707.85 - 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 707.85 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 707.85, so we can write it down as 100%=707.85.
4. We know, that x% equals 0.15 of the output value, so we can write it down as x%=0.15.
5. Now we have two simple equations:
1) 100%=707.85
2) x%=0.15
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%=707.85/0.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.15 is what percent of 707.85

100%/x%=707.85/0.15
(100/x)*x=(707.85/0.15)*x       - we multiply both sides of the equation by x
100=4719*x       - we divide both sides of the equation by (4719) to get x
100/4719=x
0.021190930281839=x
x=0.021190930281839

now we have:
0.15 is 0.021190930281839% of 707.85
