63 is what percent of 313 - 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 313 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 313, so we can write it down as 100%=313.
4. We know, that x% equals 63 of the output value, so we can write it down as x%=63.
5. Now we have two simple equations:
1) 100%=313
2) x%=63
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%=313/63
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 63 is what percent of 313

100%/x%=313/63
(100/x)*x=(313/63)*x       - we multiply both sides of the equation by x
100=4.968253968254*x       - we divide both sides of the equation by (4.968253968254) to get x
100/4.968253968254=x
20.127795527157=x
x=20.127795527157

now we have:
63 is 20.127795527157% of 313
