Answer:
1.We assume, that the number 520 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 520, so we can write it down as 100%=520.
4. We know, that x% equals 260 of the output value, so we can write it down as x%=260.
5. Now we have two simple equations:
1) 100%=520
2) x%=260
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%=520/260
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 260 is what percent of 520
100%/x%=520/260
(100/x)*x=(520/260)*x - we multiply both sides of the equation by x
100=2*x - we divide both sides of the equation by (2) to get x
100/2=x
50=x
x=50
now we have:
260 is 50% of 520
