69.8 is what percent of 83.4 - 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 83.4 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 83.4, so we can write it down as 100%=83.4.
4. We know, that x% equals 69.8 of the output value, so we can write it down as x%=69.8.
5. Now we have two simple equations:
1) 100%=83.4
2) x%=69.8
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%=83.4/69.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 69.8 is what percent of 83.4

100%/x%=83.4/69.8
(100/x)*x=(83.4/69.8)*x       - we multiply both sides of the equation by x
100=1.1948424068768*x       - we divide both sides of the equation by (1.1948424068768) to get x
100/1.1948424068768=x
83.693045563549=x
x=83.693045563549

now we have:
69.8 is 83.693045563549% of 83.4
