50.45 is what percent of 69.99 - 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 69.99 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 69.99, so we can write it down as 100%=69.99.
4. We know, that x% equals 50.45 of the output value, so we can write it down as x%=50.45.
5. Now we have two simple equations:
1) 100%=69.99
2) x%=50.45
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%=69.99/50.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 50.45 is what percent of 69.99

100%/x%=69.99/50.45
(100/x)*x=(69.99/50.45)*x       - we multiply both sides of the equation by x
100=1.387314172448*x       - we divide both sides of the equation by (1.387314172448) to get x
100/1.387314172448=x
72.081725960852=x
x=72.081725960852

now we have:
50.45 is 72.081725960852% of 69.99
