72 is what percent of 1630 - 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 1630 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 1630, so we can write it down as 100%=1630.
4. We know, that x% equals 72 of the output value, so we can write it down as x%=72.
5. Now we have two simple equations:
1) 100%=1630
2) x%=72
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%=1630/72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 72 is what percent of 1630

100%/x%=1630/72
(100/x)*x=(1630/72)*x       - we multiply both sides of the equation by x
100=22.638888888889*x       - we divide both sides of the equation by (22.638888888889) to get x
100/22.638888888889=x
4.4171779141104=x
x=4.4171779141104

now we have:
72 is 4.4171779141104% of 1630
