133.4 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 133.4 of the output value, so we can write it down as x%=133.4.
5. Now we have two simple equations:
1) 100%=448
2) x%=133.4
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%=448/133.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 133.4 is what percent of 448

100%/x%=448/133.4
(100/x)*x=(448/133.4)*x       - we multiply both sides of the equation by x
100=3.3583208395802*x       - we divide both sides of the equation by (3.3583208395802) to get x
100/3.3583208395802=x
29.776785714286=x
x=29.776785714286

now we have:
133.4 is 29.776785714286% of 448
