0.49 is what percent of 0.78 - 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 0.78 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 0.78, so we can write it down as 100%=0.78.
4. We know, that x% equals 0.49 of the output value, so we can write it down as x%=0.49.
5. Now we have two simple equations:
1) 100%=0.78
2) x%=0.49
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%=0.78/0.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.49 is what percent of 0.78

100%/x%=0.78/0.49
(100/x)*x=(0.78/0.49)*x       - we multiply both sides of the equation by x
100=1.5918367346939*x       - we divide both sides of the equation by (1.5918367346939) to get x
100/1.5918367346939=x
62.820512820513=x
x=62.820512820513

now we have:
0.49 is 62.820512820513% of 0.78
