0.78 is what percent of 22 - 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 22 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 22, so we can write it down as 100%=22.
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%=22
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%=22/0.78
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 22

100%/x%=22/0.78
(100/x)*x=(22/0.78)*x       - we multiply both sides of the equation by x
100=28.205128205128*x       - we divide both sides of the equation by (28.205128205128) to get x
100/28.205128205128=x
3.5454545454545=x
x=3.5454545454545

now we have:
0.78 is 3.5454545454545% of 22
