0.67 is what percent of 3.5 - 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 3.5 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 3.5, so we can write it down as 100%=3.5.
4. We know, that x% equals 0.67 of the output value, so we can write it down as x%=0.67.
5. Now we have two simple equations:
1) 100%=3.5
2) x%=0.67
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%=3.5/0.67
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.67 is what percent of 3.5

100%/x%=3.5/0.67
(100/x)*x=(3.5/0.67)*x       - we multiply both sides of the equation by x
100=5.2238805970149*x       - we divide both sides of the equation by (5.2238805970149) to get x
100/5.2238805970149=x
19.142857142857=x
x=19.142857142857

now we have:
0.67 is 19.142857142857% of 3.5
