1.9 is what percent of 7.5 - 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 7.5 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 7.5, so we can write it down as 100%=7.5.
4. We know, that x% equals 1.9 of the output value, so we can write it down as x%=1.9.
5. Now we have two simple equations:
1) 100%=7.5
2) x%=1.9
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%=7.5/1.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.9 is what percent of 7.5

100%/x%=7.5/1.9
(100/x)*x=(7.5/1.9)*x       - we multiply both sides of the equation by x
100=3.9473684210526*x       - we divide both sides of the equation by (3.9473684210526) to get x
100/3.9473684210526=x
25.333333333333=x
x=25.333333333333

now we have:
1.9 is 25.333333333333% of 7.5
