What is 66.66 percent of 870 - 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 870 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 870 is 100%, so we can write it down as 870=100%.
4. We know, that x is 66.66% of the output value, so we can write it down as x=66.66%.
5. Now we have two simple equations:
1) 870=100%
2) x=66.66%
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:
870/x=100%/66.66%
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 66.66% of 870

870/x=100/66.66
(870/x)*x=(100/66.66)*x       - we multiply both sides of the equation by x
870=1.5001500150015*x       - we divide both sides of the equation by (1.5001500150015) to get x
870/1.5001500150015=x
579.942=x
x=579.942

now we have:
66.66% of 870=579.942
