7.49 is what percent of 155 - 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 155 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 155, so we can write it down as 100%=155.
4. We know, that x% equals 7.49 of the output value, so we can write it down as x%=7.49.
5. Now we have two simple equations:
1) 100%=155
2) x%=7.49
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%=155/7.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.49 is what percent of 155

100%/x%=155/7.49
(100/x)*x=(155/7.49)*x       - we multiply both sides of the equation by x
100=20.694259012016*x       - we divide both sides of the equation by (20.694259012016) to get x
100/20.694259012016=x
4.8322580645161=x
x=4.8322580645161

now we have:
7.49 is 4.8322580645161% of 155
