19 is what percent of 29.45 - 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 29.45 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 29.45, so we can write it down as 100%=29.45.
4. We know, that x% equals 19 of the output value, so we can write it down as x%=19.
5. Now we have two simple equations:
1) 100%=29.45
2) x%=19
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%=29.45/19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19 is what percent of 29.45

100%/x%=29.45/19
(100/x)*x=(29.45/19)*x       - we multiply both sides of the equation by x
100=1.55*x       - we divide both sides of the equation by (1.55) to get x
100/1.55=x
64.516129032258=x
x=64.516129032258

now we have:
19 is 64.516129032258% of 29.45
