5.45 is what percent of 69.76 - 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 69.76 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 69.76, so we can write it down as 100%=69.76.
4. We know, that x% equals 5.45 of the output value, so we can write it down as x%=5.45.
5. Now we have two simple equations:
1) 100%=69.76
2) x%=5.45
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%=69.76/5.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.45 is what percent of 69.76

100%/x%=69.76/5.45
(100/x)*x=(69.76/5.45)*x       - we multiply both sides of the equation by x
100=12.8*x       - we divide both sides of the equation by (12.8) to get x
100/12.8=x
7.8125=x
x=7.8125

now we have:
5.45 is 7.8125% of 69.76
