2.68 is what percent of 3.98 - 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 3.98 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 3.98, so we can write it down as 100%=3.98.
4. We know, that x% equals 2.68 of the output value, so we can write it down as x%=2.68.
5. Now we have two simple equations:
1) 100%=3.98
2) x%=2.68
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%=3.98/2.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.68 is what percent of 3.98

100%/x%=3.98/2.68
(100/x)*x=(3.98/2.68)*x       - we multiply both sides of the equation by x
100=1.4850746268657*x       - we divide both sides of the equation by (1.4850746268657) to get x
100/1.4850746268657=x
67.336683417085=x
x=67.336683417085

now we have:
2.68 is 67.336683417085% of 3.98
