10.5 is what percent of 133 - 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 133 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 133, so we can write it down as 100%=133.
4. We know, that x% equals 10.5 of the output value, so we can write it down as x%=10.5.
5. Now we have two simple equations:
1) 100%=133
2) x%=10.5
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%=133/10.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.5 is what percent of 133

100%/x%=133/10.5
(100/x)*x=(133/10.5)*x       - we multiply both sides of the equation by x
100=12.666666666667*x       - we divide both sides of the equation by (12.666666666667) to get x
100/12.666666666667=x
7.8947368421053=x
x=7.8947368421053

now we have:
10.5 is 7.8947368421053% of 133
