3.21 is what percent of 18.3 - 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 18.3 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 18.3, so we can write it down as 100%=18.3.
4. We know, that x% equals 3.21 of the output value, so we can write it down as x%=3.21.
5. Now we have two simple equations:
1) 100%=18.3
2) x%=3.21
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%=18.3/3.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.21 is what percent of 18.3

100%/x%=18.3/3.21
(100/x)*x=(18.3/3.21)*x       - we multiply both sides of the equation by x
100=5.7009345794393*x       - we divide both sides of the equation by (5.7009345794393) to get x
100/5.7009345794393=x
17.540983606557=x
x=17.540983606557

now we have:
3.21 is 17.540983606557% of 18.3
