17.9 is what percent of 30.1 - 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 30.1 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 30.1, so we can write it down as 100%=30.1.
4. We know, that x% equals 17.9 of the output value, so we can write it down as x%=17.9.
5. Now we have two simple equations:
1) 100%=30.1
2) x%=17.9
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%=30.1/17.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.9 is what percent of 30.1

100%/x%=30.1/17.9
(100/x)*x=(30.1/17.9)*x       - we multiply both sides of the equation by x
100=1.6815642458101*x       - we divide both sides of the equation by (1.6815642458101) to get x
100/1.6815642458101=x
59.468438538206=x
x=59.468438538206

now we have:
17.9 is 59.468438538206% of 30.1
