73 is what percent of 1820 - 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 1820 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 1820, so we can write it down as 100%=1820.
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%=1820
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%=1820/73
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 1820

100%/x%=1820/73
(100/x)*x=(1820/73)*x       - we multiply both sides of the equation by x
100=24.931506849315*x       - we divide both sides of the equation by (24.931506849315) to get x
100/24.931506849315=x
4.010989010989=x
x=4.010989010989

now we have:
73 is 4.010989010989% of 1820
