3.36 is what percent of 2.1 - 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 2.1 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 2.1, so we can write it down as 100%=2.1.
4. We know, that x% equals 3.36 of the output value, so we can write it down as x%=3.36.
5. Now we have two simple equations:
1) 100%=2.1
2) x%=3.36
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%=2.1/3.36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.36 is what percent of 2.1

100%/x%=2.1/3.36
(100/x)*x=(2.1/3.36)*x       - we multiply both sides of the equation by x
100=0.625*x       - we divide both sides of the equation by (0.625) to get x
100/0.625=x
160=x
x=160

now we have:
3.36 is 160% of 2.1
