15 is what percent of 1675 - 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 1675 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 1675, so we can write it down as 100%=1675.
4. We know, that x% equals 15 of the output value, so we can write it down as x%=15.
5. Now we have two simple equations:
1) 100%=1675
2) x%=15
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%=1675/15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15 is what percent of 1675

100%/x%=1675/15
(100/x)*x=(1675/15)*x       - we multiply both sides of the equation by x
100=111.66666666667*x       - we divide both sides of the equation by (111.66666666667) to get x
100/111.66666666667=x
0.8955223880597=x
x=0.8955223880597

now we have:
15 is 0.8955223880597% of 1675
