7.7 is what percent of 249 - 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 249 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 249, so we can write it down as 100%=249.
4. We know, that x% equals 7.7 of the output value, so we can write it down as x%=7.7.
5. Now we have two simple equations:
1) 100%=249
2) x%=7.7
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%=249/7.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.7 is what percent of 249

100%/x%=249/7.7
(100/x)*x=(249/7.7)*x       - we multiply both sides of the equation by x
100=32.337662337662*x       - we divide both sides of the equation by (32.337662337662) to get x
100/32.337662337662=x
3.0923694779116=x
x=3.0923694779116

now we have:
7.7 is 3.0923694779116% of 249
