32 is what percent of 19.78 - 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 19.78 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 19.78, so we can write it down as 100%=19.78.
4. We know, that x% equals 32 of the output value, so we can write it down as x%=32.
5. Now we have two simple equations:
1) 100%=19.78
2) x%=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%=19.78/32
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 32 is what percent of 19.78

100%/x%=19.78/32
(100/x)*x=(19.78/32)*x       - we multiply both sides of the equation by x
100=0.618125*x       - we divide both sides of the equation by (0.618125) to get x
100/0.618125=x
161.77957532861=x
x=161.77957532861

now we have:
32 is 161.77957532861% of 19.78
