What is 991 percent of 1021 - 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 1021 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 1021 is 100%, so we can write it down as 1021=100%.
4. We know, that x is 991% of the output value, so we can write it down as x=991%.
5. Now we have two simple equations:
1) 1021=100%
2) x=991%
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:
1021/x=100%/991%
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 991% of 1021

1021/x=100/991
(1021/x)*x=(100/991)*x       - we multiply both sides of the equation by x
1021=0.10090817356206*x       - we divide both sides of the equation by (0.10090817356206) to get x
1021/0.10090817356206=x
10118.11=x
x=10118.11

now we have:
991% of 1021=10118.11
