0.32 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 0.32 of the output value, so we can write it down as x%=0.32.
5. Now we have two simple equations:
1) 100%=6.4
2) x%=0.32
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%=6.4/0.32
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.32 is what percent of 6.4

100%/x%=6.4/0.32
(100/x)*x=(6.4/0.32)*x       - we multiply both sides of the equation by x
100=20*x       - we divide both sides of the equation by (20) to get x
100/20=x
5=x
x=5

now we have:
0.32 is 5% of 6.4
