8.7 is what percent of 1204 - 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 1204 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 1204, so we can write it down as 100%=1204.
4. We know, that x% equals 8.7 of the output value, so we can write it down as x%=8.7.
5. Now we have two simple equations:
1) 100%=1204
2) x%=8.7
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%=1204/8.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.7 is what percent of 1204

100%/x%=1204/8.7
(100/x)*x=(1204/8.7)*x       - we multiply both sides of the equation by x
100=138.3908045977*x       - we divide both sides of the equation by (138.3908045977) to get x
100/138.3908045977=x
0.72259136212625=x
x=0.72259136212625

now we have:
8.7 is 0.72259136212625% of 1204
