8.4 is what percent of 49.3 - 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 49.3 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 49.3, so we can write it down as 100%=49.3.
4. We know, that x% equals 8.4 of the output value, so we can write it down as x%=8.4.
5. Now we have two simple equations:
1) 100%=49.3
2) x%=8.4
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%=49.3/8.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.4 is what percent of 49.3

100%/x%=49.3/8.4
(100/x)*x=(49.3/8.4)*x       - we multiply both sides of the equation by x
100=5.8690476190476*x       - we divide both sides of the equation by (5.8690476190476) to get x
100/5.8690476190476=x
17.038539553753=x
x=17.038539553753

now we have:
8.4 is 17.038539553753% of 49.3
