19.4 is what percent of 448 - 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 448 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 448, so we can write it down as 100%=448.
4. We know, that x% equals 19.4 of the output value, so we can write it down as x%=19.4.
5. Now we have two simple equations:
1) 100%=448
2) x%=19.4
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%=448/19.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.4 is what percent of 448

100%/x%=448/19.4
(100/x)*x=(448/19.4)*x       - we multiply both sides of the equation by x
100=23.092783505155*x       - we divide both sides of the equation by (23.092783505155) to get x
100/23.092783505155=x
4.3303571428571=x
x=4.3303571428571

now we have:
19.4 is 4.3303571428571% of 448
