Answer:
165 %
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 30 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 30, so we can write it down as 100%=30.
4. We know, that x% equals 49.5 of the output value, so we can write it down as x%=49.5.
5. Now we have two simple equations:
1) 100%=30
2) x%=49.5
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%=30/49.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 49.5 is what percent of 30
100%/x%=30/49.5
(100/x)*x=(30/49.5)*x - we multiply both sides of the equation by x
100=0.60606060606061*x - we divide both sides of the equation by (0.60606060606061) to get x
100/0.60606060606061=x
165=x
x=165
now we have:
49.5 is 165% of 30
