3.4 is what percent of 4.19 - 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 4.19 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 4.19, so we can write it down as 100%=4.19.
4. We know, that x% equals 3.4 of the output value, so we can write it down as x%=3.4.
5. Now we have two simple equations:
1) 100%=4.19
2) x%=3.4
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%=4.19/3.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.4 is what percent of 4.19

100%/x%=4.19/3.4
(100/x)*x=(4.19/3.4)*x       - we multiply both sides of the equation by x
100=1.2323529411765*x       - we divide both sides of the equation by (1.2323529411765) to get x
100/1.2323529411765=x
81.145584725537=x
x=81.145584725537

now we have:
3.4 is 81.145584725537% of 4.19
