49.9 is what percent of 151 - 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 151 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 151, so we can write it down as 100%=151.
4. We know, that x% equals 49.9 of the output value, so we can write it down as x%=49.9.
5. Now we have two simple equations:
1) 100%=151
2) x%=49.9
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%=151/49.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49.9 is what percent of 151

100%/x%=151/49.9
(100/x)*x=(151/49.9)*x       - we multiply both sides of the equation by x
100=3.0260521042084*x       - we divide both sides of the equation by (3.0260521042084) to get x
100/3.0260521042084=x
33.046357615894=x
x=33.046357615894

now we have:
49.9 is 33.046357615894% of 151
