What is 1.5 percent of 40 - 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 40 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 40 is 100%, so we can write it down as 40=100%.
4. We know, that x is 1.5% of the output value, so we can write it down as x=1.5%.
5. Now we have two simple equations:
1) 40=100%
2) x=1.5%
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:
40/x=100%/1.5%
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 1.5% of 40

40/x=100/1.5
(40/x)*x=(100/1.5)*x       - we multiply both sides of the equation by x
40=66.6666666667*x       - we divide both sides of the equation by (66.6666666667) to get x
40/66.6666666667=x
0.6=x
x=0.6

now we have:
1.5% of 40=0.6
