27.9 is what percent of 88 - 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 88 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 88, so we can write it down as 100%=88.
4. We know, that x% equals 27.9 of the output value, so we can write it down as x%=27.9.
5. Now we have two simple equations:
1) 100%=88
2) x%=27.9
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%=88/27.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27.9 is what percent of 88

100%/x%=88/27.9
(100/x)*x=(88/27.9)*x       - we multiply both sides of the equation by x
100=3.1541218637993*x       - we divide both sides of the equation by (3.1541218637993) to get x
100/3.1541218637993=x
31.704545454545=x
x=31.704545454545

now we have:
27.9 is 31.704545454545% of 88
