393.7 is what percent of 2720 - 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 2720 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 2720, so we can write it down as 100%=2720.
4. We know, that x% equals 393.7 of the output value, so we can write it down as x%=393.7.
5. Now we have two simple equations:
1) 100%=2720
2) x%=393.7
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%=2720/393.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 393.7 is what percent of 2720

100%/x%=2720/393.7
(100/x)*x=(2720/393.7)*x       - we multiply both sides of the equation by x
100=6.9088138176276*x       - we divide both sides of the equation by (6.9088138176276) to get x
100/6.9088138176276=x
14.474264705882=x
x=14.474264705882

now we have:
393.7 is 14.474264705882% of 2720
