1678.8 is what percent of 839.28 - 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 839.28 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 839.28, so we can write it down as 100%=839.28.
4. We know, that x% equals 1678.8 of the output value, so we can write it down as x%=1678.8.
5. Now we have two simple equations:
1) 100%=839.28
2) x%=1678.8
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%=839.28/1678.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1678.8 is what percent of 839.28

(100/x)*x=(839.28/1678.8)*x       - we multiply both sides of the equation by x
100=0.49992852037169*x       - we divide both sides of the equation by (0.49992852037169) to get x
100/0.49992852037169=x
200.02859593938=x
x=200.02859593938

now we have:
