1.58 is what percent of 18.7 - 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 18.7 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 18.7, so we can write it down as 100%=18.7.
4. We know, that x% equals 1.58 of the output value, so we can write it down as x%=1.58.
5. Now we have two simple equations:
1) 100%=18.7
2) x%=1.58
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%=18.7/1.58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.58 is what percent of 18.7

100%/x%=18.7/1.58
(100/x)*x=(18.7/1.58)*x       - we multiply both sides of the equation by x
100=11.835443037975*x       - we divide both sides of the equation by (11.835443037975) to get x
100/11.835443037975=x
8.4491978609626=x
x=8.4491978609626

now we have:
1.58 is 8.4491978609626% of 18.7
