19.4 is what percent of 23 - 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 23 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 23, so we can write it down as 100%=23.
4. We know, that x% equals 19.4 of the output value, so we can write it down as x%=19.4.
5. Now we have two simple equations:
1) 100%=23
2) x%=19.4
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%=23/19.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.4 is what percent of 23

100%/x%=23/19.4
(100/x)*x=(23/19.4)*x       - we multiply both sides of the equation by x
100=1.1855670103093*x       - we divide both sides of the equation by (1.1855670103093) to get x
100/1.1855670103093=x
84.347826086957=x
x=84.347826086957

now we have:
19.4 is 84.347826086957% of 23
