49 is what percent of 139.99 - 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 139.99 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 139.99, so we can write it down as 100%=139.99.
4. We know, that x% equals 49 of the output value, so we can write it down as x%=49.
5. Now we have two simple equations:
1) 100%=139.99
2) x%=49
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%=139.99/49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49 is what percent of 139.99

100%/x%=139.99/49
(100/x)*x=(139.99/49)*x       - we multiply both sides of the equation by x
100=2.8569387755102*x       - we divide both sides of the equation by (2.8569387755102) to get x
100/2.8569387755102=x
35.002500178584=x
x=35.002500178584

now we have:
49 is 35.002500178584% of 139.99
