5.55 is what percent of 19.45 - 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 19.45 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 19.45, so we can write it down as 100%=19.45.
4. We know, that x% equals 5.55 of the output value, so we can write it down as x%=5.55.
5. Now we have two simple equations:
1) 100%=19.45
2) x%=5.55
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%=19.45/5.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.55 is what percent of 19.45

100%/x%=19.45/5.55
(100/x)*x=(19.45/5.55)*x       - we multiply both sides of the equation by x
100=3.5045045045045*x       - we divide both sides of the equation by (3.5045045045045) to get x
100/3.5045045045045=x
28.53470437018=x
x=28.53470437018

now we have:
5.55 is 28.53470437018% of 19.45
