30 is what percent of 476 - 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 476 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 476, so we can write it down as 100%=476.
4. We know, that x% equals 30 of the output value, so we can write it down as x%=30.
5. Now we have two simple equations:
1) 100%=476
2) x%=30
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%=476/30
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30 is what percent of 476

100%/x%=476/30
(100/x)*x=(476/30)*x       - we multiply both sides of the equation by x
100=15.866666666667*x       - we divide both sides of the equation by (15.866666666667) to get x
100/15.866666666667=x
6.3025210084034=x
x=6.3025210084034

now we have:
30 is 6.3025210084034% of 476
