4.3 is what percent of 4.9 - 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 4.9 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 4.9, so we can write it down as 100%=4.9.
4. We know, that x% equals 4.3 of the output value, so we can write it down as x%=4.3.
5. Now we have two simple equations:
1) 100%=4.9
2) x%=4.3
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%=4.9/4.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.3 is what percent of 4.9

100%/x%=4.9/4.3
(100/x)*x=(4.9/4.3)*x       - we multiply both sides of the equation by x
100=1.1395348837209*x       - we divide both sides of the equation by (1.1395348837209) to get x
100/1.1395348837209=x
87.755102040816=x
x=87.755102040816

now we have:
4.3 is 87.755102040816% of 4.9
