0.69 is what percent of 1.45 - 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 1.45 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 1.45, so we can write it down as 100%=1.45.
4. We know, that x% equals 0.69 of the output value, so we can write it down as x%=0.69.
5. Now we have two simple equations:
1) 100%=1.45
2) x%=0.69
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%=1.45/0.69
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.69 is what percent of 1.45

100%/x%=1.45/0.69
(100/x)*x=(1.45/0.69)*x       - we multiply both sides of the equation by x
100=2.1014492753623*x       - we divide both sides of the equation by (2.1014492753623) to get x
100/2.1014492753623=x
47.586206896552=x
x=47.586206896552

now we have:
0.69 is 47.586206896552% of 1.45
