53 is what percent of 311 - 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 311 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 311, so we can write it down as 100%=311.
4. We know, that x% equals 53 of the output value, so we can write it down as x%=53.
5. Now we have two simple equations:
1) 100%=311
2) x%=53
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%=311/53
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 53 is what percent of 311

100%/x%=311/53
(100/x)*x=(311/53)*x       - we multiply both sides of the equation by x
100=5.8679245283019*x       - we divide both sides of the equation by (5.8679245283019) to get x
100/5.8679245283019=x
17.041800643087=x
x=17.041800643087

now we have:
53 is 17.041800643087% of 311
