6.43 is what percent of 330 - 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 330 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 330, so we can write it down as 100%=330.
4. We know, that x% equals 6.43 of the output value, so we can write it down as x%=6.43.
5. Now we have two simple equations:
1) 100%=330
2) x%=6.43
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%=330/6.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.43 is what percent of 330

100%/x%=330/6.43
(100/x)*x=(330/6.43)*x       - we multiply both sides of the equation by x
100=51.321928460342*x       - we divide both sides of the equation by (51.321928460342) to get x
100/51.321928460342=x
1.9484848484848=x
x=1.9484848484848

now we have:
6.43 is 1.9484848484848% of 330
