73 is what percent of 1245 - 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 1245 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 1245, so we can write it down as 100%=1245.
4. We know, that x% equals 73 of the output value, so we can write it down as x%=73.
5. Now we have two simple equations:
1) 100%=1245
2) x%=73
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%=1245/73
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 73 is what percent of 1245

100%/x%=1245/73
(100/x)*x=(1245/73)*x       - we multiply both sides of the equation by x
100=17.054794520548*x       - we divide both sides of the equation by (17.054794520548) to get x
100/17.054794520548=x
5.863453815261=x
x=5.863453815261

now we have:
73 is 5.863453815261% of 1245
