247.57 is what percent of 279.3 - 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 279.3 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 279.3, so we can write it down as 100%=279.3.
4. We know, that x% equals 247.57 of the output value, so we can write it down as x%=247.57.
5. Now we have two simple equations:
1) 100%=279.3
2) x%=247.57
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%=279.3/247.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 247.57 is what percent of 279.3

100%/x%=279.3/247.57
(100/x)*x=(279.3/247.57)*x       - we multiply both sides of the equation by x
100=1.128165771297*x       - we divide both sides of the equation by (1.128165771297) to get x
100/1.128165771297=x
88.639455782313=x
x=88.639455782313

now we have:
247.57 is 88.639455782313% of 279.3
