0.65 is what percent of 1.55 - 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 1.55 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 1.55, so we can write it down as 100%=1.55.
4. We know, that x% equals 0.65 of the output value, so we can write it down as x%=0.65.
5. Now we have two simple equations:
1) 100%=1.55
2) x%=0.65
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%=1.55/0.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.65 is what percent of 1.55

100%/x%=1.55/0.65
(100/x)*x=(1.55/0.65)*x       - we multiply both sides of the equation by x
100=2.3846153846154*x       - we divide both sides of the equation by (2.3846153846154) to get x
100/2.3846153846154=x
41.935483870968=x
x=41.935483870968

now we have:
0.65 is 41.935483870968% of 1.55
