0.78 is what percent of 2.82 - 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 2.82 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 2.82, so we can write it down as 100%=2.82.
4. We know, that x% equals 0.78 of the output value, so we can write it down as x%=0.78.
5. Now we have two simple equations:
1) 100%=2.82
2) x%=0.78
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%=2.82/0.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.78 is what percent of 2.82

100%/x%=2.82/0.78
(100/x)*x=(2.82/0.78)*x       - we multiply both sides of the equation by x
100=3.6153846153846*x       - we divide both sides of the equation by (3.6153846153846) to get x
100/3.6153846153846=x
27.659574468085=x
x=27.659574468085

now we have:
0.78 is 27.659574468085% of 2.82
