49 is what percent of 1042 - 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 1042 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 1042, so we can write it down as 100%=1042.
4. We know, that x% equals 49 of the output value, so we can write it down as x%=49.
5. Now we have two simple equations:
1) 100%=1042
2) x%=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%=1042/49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49 is what percent of 1042

100%/x%=1042/49
(100/x)*x=(1042/49)*x       - we multiply both sides of the equation by x
100=21.265306122449*x       - we divide both sides of the equation by (21.265306122449) to get x
100/21.265306122449=x
4.7024952015355=x
x=4.7024952015355

now we have:
49 is 4.7024952015355% of 1042
