0.89 is what percent of 27.89 - 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 27.89 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 27.89, so we can write it down as 100%=27.89.
4. We know, that x% equals 0.89 of the output value, so we can write it down as x%=0.89.
5. Now we have two simple equations:
1) 100%=27.89
2) x%=0.89
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%=27.89/0.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.89 is what percent of 27.89

100%/x%=27.89/0.89
(100/x)*x=(27.89/0.89)*x       - we multiply both sides of the equation by x
100=31.337078651685*x       - we divide both sides of the equation by (31.337078651685) to get x
100/31.337078651685=x
3.1911079239871=x
x=3.1911079239871

now we have:
0.89 is 3.1911079239871% of 27.89
