1.55 is what percent of 1.7 - 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 1.7 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 1.7, so we can write it down as 100%=1.7.
4. We know, that x% equals 1.55 of the output value, so we can write it down as x%=1.55.
5. Now we have two simple equations:
1) 100%=1.7
2) x%=1.55
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%=1.7/1.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.55 is what percent of 1.7

100%/x%=1.7/1.55
(100/x)*x=(1.7/1.55)*x       - we multiply both sides of the equation by x
100=1.0967741935484*x       - we divide both sides of the equation by (1.0967741935484) to get x
100/1.0967741935484=x
91.176470588235=x
x=91.176470588235

now we have:
1.55 is 91.176470588235% of 1.7
