622.4 is what percent of 964.72 - 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 964.72 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 964.72, so we can write it down as 100%=964.72.
4. We know, that x% equals 622.4 of the output value, so we can write it down as x%=622.4.
5. Now we have two simple equations:
1) 100%=964.72
2) x%=622.4
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%=964.72/622.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 622.4 is what percent of 964.72

100%/x%=964.72/622.4
(100/x)*x=(964.72/622.4)*x       - we multiply both sides of the equation by x
100=1.55*x       - we divide both sides of the equation by (1.55) to get x
100/1.55=x
64.516129032258=x
x=64.516129032258

now we have:
622.4 is 64.516129032258% of 964.72
