42.9 is what percent of 32 - 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 32 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 32, so we can write it down as 100%=32.
4. We know, that x% equals 42.9 of the output value, so we can write it down as x%=42.9.
5. Now we have two simple equations:
1) 100%=32
2) x%=42.9
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%=32/42.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.9 is what percent of 32

100%/x%=32/42.9
(100/x)*x=(32/42.9)*x       - we multiply both sides of the equation by x
100=0.74592074592075*x       - we divide both sides of the equation by (0.74592074592075) to get x
100/0.74592074592075=x
134.0625=x
x=134.0625

now we have:
42.9 is 134.0625% of 32
