79.4 is what percent of 154 - 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 154 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 154, so we can write it down as 100%=154.
4. We know, that x% equals 79.4 of the output value, so we can write it down as x%=79.4.
5. Now we have two simple equations:
1) 100%=154
2) x%=79.4
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%=154/79.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79.4 is what percent of 154

100%/x%=154/79.4
(100/x)*x=(154/79.4)*x       - we multiply both sides of the equation by x
100=1.9395465994962*x       - we divide both sides of the equation by (1.9395465994962) to get x
100/1.9395465994962=x
51.558441558442=x
x=51.558441558442

now we have:
79.4 is 51.558441558442% of 154
