133 is what percent of 1233 - 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 1233 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 1233, so we can write it down as 100%=1233.
4. We know, that x% equals 133 of the output value, so we can write it down as x%=133.
5. Now we have two simple equations:
1) 100%=1233
2) x%=133
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%=1233/133
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 133 is what percent of 1233

100%/x%=1233/133
(100/x)*x=(1233/133)*x       - we multiply both sides of the equation by x
100=9.2706766917293*x       - we divide both sides of the equation by (9.2706766917293) to get x
100/9.2706766917293=x
10.786699107867=x
x=10.786699107867

now we have:
133 is 10.786699107867% of 1233
