What is 1.3 percent of 1615 - 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 1615 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 1615 is 100%, so we can write it down as 1615=100%.
4. We know, that x is 1.3% of the output value, so we can write it down as x=1.3%.
5. Now we have two simple equations:
1) 1615=100%
2) x=1.3%
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:
1615/x=100%/1.3%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 1.3% of 1615

1615/x=100/1.3
(1615/x)*x=(100/1.3)*x       - we multiply both sides of the equation by x
1615=76.923076923077*x       - we divide both sides of the equation by (76.923076923077) to get x
1615/76.923076923077=x
20.995=x
x=20.995

now we have:
1.3% of 1615=20.995
