719.19 is what percent of 878.4 - 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 878.4 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 878.4, so we can write it down as 100%=878.4.
4. We know, that x% equals 719.19 of the output value, so we can write it down as x%=719.19.
5. Now we have two simple equations:
1) 100%=878.4
2) x%=719.19
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%=878.4/719.19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 719.19 is what percent of 878.4

100%/x%=878.4/719.19
(100/x)*x=(878.4/719.19)*x       - we multiply both sides of the equation by x
100=1.2213740458015*x       - we divide both sides of the equation by (1.2213740458015) to get x
100/1.2213740458015=x
81.875=x
x=81.875

now we have:
719.19 is 81.875% of 878.4
