843.5 is what percent of 978.46 - 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 978.46 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 978.46, so we can write it down as 100%=978.46.
4. We know, that x% equals 843.5 of the output value, so we can write it down as x%=843.5.
5. Now we have two simple equations:
1) 100%=978.46
2) x%=843.5
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%=978.46/843.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 843.5 is what percent of 978.46

100%/x%=978.46/843.5
(100/x)*x=(978.46/843.5)*x       - we multiply both sides of the equation by x
100=1.16*x       - we divide both sides of the equation by (1.16) to get x
100/1.16=x
86.206896551724=x
x=86.206896551724

now we have:
843.5 is 86.206896551724% of 978.46
