30 is what percent of 7380 - 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 7380 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 7380, so we can write it down as 100%=7380.
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%=7380
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%=7380/30
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 7380

100%/x%=7380/30
(100/x)*x=(7380/30)*x       - we multiply both sides of the equation by x
100=246*x       - we divide both sides of the equation by (246) to get x
100/246=x
0.40650406504065=x
x=0.40650406504065

now we have:
30 is 0.40650406504065% of 7380
