17.4 is what percent of 921 - 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 921 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 921, so we can write it down as 100%=921.
4. We know, that x% equals 17.4 of the output value, so we can write it down as x%=17.4.
5. Now we have two simple equations:
1) 100%=921
2) x%=17.4
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%=921/17.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.4 is what percent of 921

100%/x%=921/17.4
(100/x)*x=(921/17.4)*x       - we multiply both sides of the equation by x
100=52.931034482759*x       - we divide both sides of the equation by (52.931034482759) to get x
100/52.931034482759=x
1.8892508143322=x
x=1.8892508143322

now we have:
17.4 is 1.8892508143322% of 921
