7.6 is what percent of 42.7 - 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 42.7 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 42.7, so we can write it down as 100%=42.7.
4. We know, that x% equals 7.6 of the output value, so we can write it down as x%=7.6.
5. Now we have two simple equations:
1) 100%=42.7
2) x%=7.6
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%=42.7/7.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.6 is what percent of 42.7

100%/x%=42.7/7.6
(100/x)*x=(42.7/7.6)*x       - we multiply both sides of the equation by x
100=5.6184210526316*x       - we divide both sides of the equation by (5.6184210526316) to get x
100/5.6184210526316=x
17.798594847775=x
x=17.798594847775

now we have:
7.6 is 17.798594847775% of 42.7
