3.43 is what percent of 17.21 - 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 17.21 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 17.21, so we can write it down as 100%=17.21.
4. We know, that x% equals 3.43 of the output value, so we can write it down as x%=3.43.
5. Now we have two simple equations:
1) 100%=17.21
2) x%=3.43
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%=17.21/3.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.43 is what percent of 17.21

100%/x%=17.21/3.43
(100/x)*x=(17.21/3.43)*x       - we multiply both sides of the equation by x
100=5.0174927113703*x       - we divide both sides of the equation by (5.0174927113703) to get x
100/5.0174927113703=x
19.930273097037=x
x=19.930273097037

now we have:
3.43 is 19.930273097037% of 17.21
