What is 900 percent of 691 - 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 691 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 691 is 100%, so we can write it down as 691=100%.
4. We know, that x is 900% of the output value, so we can write it down as x=900%.
5. Now we have two simple equations:
1) 691=100%
2) x=900%
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:
691/x=100%/900%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 900% of 691

691/x=100/900
(691/x)*x=(100/900)*x       - we multiply both sides of the equation by x
691=0.11111111111111*x       - we divide both sides of the equation by (0.11111111111111) to get x
691/0.11111111111111=x
6219=x
x=6219

now we have:
900% of 691=6219
