1.7 is what percent of 8.7 - 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 8.7 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 8.7, so we can write it down as 100%=8.7.
4. We know, that x% equals 1.7 of the output value, so we can write it down as x%=1.7.
5. Now we have two simple equations:
1) 100%=8.7
2) x%=1.7
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%=8.7/1.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.7 is what percent of 8.7

100%/x%=8.7/1.7
(100/x)*x=(8.7/1.7)*x       - we multiply both sides of the equation by x
100=5.1176470588235*x       - we divide both sides of the equation by (5.1176470588235) to get x
100/5.1176470588235=x
19.540229885057=x
x=19.540229885057

now we have:
1.7 is 19.540229885057% of 8.7
