1.2 is what percent of 2.78 - 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 2.78 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 2.78, so we can write it down as 100%=2.78.
4. We know, that x% equals 1.2 of the output value, so we can write it down as x%=1.2.
5. Now we have two simple equations:
1) 100%=2.78
2) x%=1.2
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%=2.78/1.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.2 is what percent of 2.78

100%/x%=2.78/1.2
(100/x)*x=(2.78/1.2)*x       - we multiply both sides of the equation by x
100=2.3166666666667*x       - we divide both sides of the equation by (2.3166666666667) to get x
100/2.3166666666667=x
43.165467625899=x
x=43.165467625899

now we have:
1.2 is 43.165467625899% of 2.78
