43 is what percent of 627 - 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 627 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 627, so we can write it down as 100%=627.
4. We know, that x% equals 43 of the output value, so we can write it down as x%=43.
5. Now we have two simple equations:
1) 100%=627
2) x%=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%=627/43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43 is what percent of 627

100%/x%=627/43
(100/x)*x=(627/43)*x       - we multiply both sides of the equation by x
100=14.581395348837*x       - we divide both sides of the equation by (14.581395348837) to get x
100/14.581395348837=x
6.8580542264753=x
x=6.8580542264753

now we have:
43 is 6.8580542264753% of 627
