10500 is what percent of 7 - 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 7 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 7, so we can write it down as 100%=7.
4. We know, that x% equals 10500 of the output value, so we can write it down as x%=10500.
5. Now we have two simple equations:
1) 100%=7
2) x%=10500
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%=7/10500
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10500 is what percent of 7

100%/x%=7/10500
(100/x)*x=(7/10500)*x       - we multiply both sides of the equation by x
100=0.00066666666666667*x       - we divide both sides of the equation by (0.00066666666666667) to get x
100/0.00066666666666667=x
150000=x
x=150000

now we have:
10500 is 150000% of 7
