0.54 is what percent of 1.21 - 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 1.21 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 1.21, so we can write it down as 100%=1.21.
4. We know, that x% equals 0.54 of the output value, so we can write it down as x%=0.54.
5. Now we have two simple equations:
1) 100%=1.21
2) x%=0.54
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%=1.21/0.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.54 is what percent of 1.21

100%/x%=1.21/0.54
(100/x)*x=(1.21/0.54)*x       - we multiply both sides of the equation by x
100=2.2407407407407*x       - we divide both sides of the equation by (2.2407407407407) to get x
100/2.2407407407407=x
44.628099173554=x
x=44.628099173554

now we have:
0.54 is 44.628099173554% of 1.21
