4.2 is what percent of 224 - 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 224 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 224, so we can write it down as 100%=224.
4. We know, that x% equals 4.2 of the output value, so we can write it down as x%=4.2.
5. Now we have two simple equations:
1) 100%=224
2) x%=4.2
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%=224/4.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.2 is what percent of 224

100%/x%=224/4.2
(100/x)*x=(224/4.2)*x       - we multiply both sides of the equation by x
100=53.333333333333*x       - we divide both sides of the equation by (53.333333333333) to get x
100/53.333333333333=x
1.875=x
x=1.875

now we have:
4.2 is 1.875% of 224
