1.55 is what percent of 21.17 - 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 21.17 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 21.17, so we can write it down as 100%=21.17.
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%=21.17
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%=21.17/1.55
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 21.17

100%/x%=21.17/1.55
(100/x)*x=(21.17/1.55)*x       - we multiply both sides of the equation by x
100=13.658064516129*x       - we divide both sides of the equation by (13.658064516129) to get x
100/13.658064516129=x
7.321681624941=x
x=7.321681624941

now we have:
1.55 is 7.321681624941% of 21.17
