9.64 is what percent of 6.4 - 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 6.4 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 6.4, so we can write it down as 100%=6.4.
4. We know, that x% equals 9.64 of the output value, so we can write it down as x%=9.64.
5. Now we have two simple equations:
1) 100%=6.4
2) x%=9.64
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%=6.4/9.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.64 is what percent of 6.4

100%/x%=6.4/9.64
(100/x)*x=(6.4/9.64)*x       - we multiply both sides of the equation by x
100=0.66390041493776*x       - we divide both sides of the equation by (0.66390041493776) to get x
100/0.66390041493776=x
150.625=x
x=150.625

now we have:
9.64 is 150.625% of 6.4
