55 is what percent of 1230 - 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 1230 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 1230, so we can write it down as 100%=1230.
4. We know, that x% equals 55 of the output value, so we can write it down as x%=55.
5. Now we have two simple equations:
1) 100%=1230
2) x%=55
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%=1230/55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55 is what percent of 1230

100%/x%=1230/55
(100/x)*x=(1230/55)*x       - we multiply both sides of the equation by x
100=22.363636363636*x       - we divide both sides of the equation by (22.363636363636) to get x
100/22.363636363636=x
4.4715447154472=x
x=4.4715447154472

now we have:
55 is 4.4715447154472% of 1230
