31 is what percent of 4153 - 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 4153 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 4153, so we can write it down as 100%=4153.
4. We know, that x% equals 31 of the output value, so we can write it down as x%=31.
5. Now we have two simple equations:
1) 100%=4153
2) x%=31
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%=4153/31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31 is what percent of 4153

100%/x%=4153/31
(100/x)*x=(4153/31)*x       - we multiply both sides of the equation by x
100=133.96774193548*x       - we divide both sides of the equation by (133.96774193548) to get x
100/133.96774193548=x
0.74644835058993=x
x=0.74644835058993

now we have:
31 is 0.74644835058993% of 4153
