0.7 is what percent of 39 - 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 39 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 39, so we can write it down as 100%=39.
4. We know, that x% equals 0.7 of the output value, so we can write it down as x%=0.7.
5. Now we have two simple equations:
1) 100%=39
2) x%=0.7
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%=39/0.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.7 is what percent of 39

100%/x%=39/0.7
(100/x)*x=(39/0.7)*x       - we multiply both sides of the equation by x
100=55.714285714286*x       - we divide both sides of the equation by (55.714285714286) to get x
100/55.714285714286=x
1.7948717948718=x
x=1.7948717948718

now we have:
0.7 is 1.7948717948718% of 39
