7.42 is what percent of 150 - 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 150 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 150, so we can write it down as 100%=150.
4. We know, that x% equals 7.42 of the output value, so we can write it down as x%=7.42.
5. Now we have two simple equations:
1) 100%=150
2) x%=7.42
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%=150/7.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.42 is what percent of 150

100%/x%=150/7.42
(100/x)*x=(150/7.42)*x       - we multiply both sides of the equation by x
100=20.215633423181*x       - we divide both sides of the equation by (20.215633423181) to get x
100/20.215633423181=x
4.9466666666667=x
x=4.9466666666667

now we have:
7.42 is 4.9466666666667% of 150
