17.81 is what percent of 101.77 - 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 101.77 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 101.77, so we can write it down as 100%=101.77.
4. We know, that x% equals 17.81 of the output value, so we can write it down as x%=17.81.
5. Now we have two simple equations:
1) 100%=101.77
2) x%=17.81
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%=101.77/17.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.81 is what percent of 101.77

100%/x%=101.77/17.81
(100/x)*x=(101.77/17.81)*x       - we multiply both sides of the equation by x
100=5.7142055025267*x       - we divide both sides of the equation by (5.7142055025267) to get x
100/5.7142055025267=x
17.50024565196=x
x=17.50024565196

now we have:
17.81 is 17.50024565196% of 101.77
