What is 40 percent of 2.9511 - 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 2.9511 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 2.9511 is 100%, so we can write it down as 2.9511=100%.
4. We know, that x is 40% of the output value, so we can write it down as x=40%.
5. Now we have two simple equations:
1) 2.9511=100%
2) x=40%
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:
2.9511/x=100%/40%
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 40% of 2.9511

2.9511/x=100/40
(2.9511/x)*x=(100/40)*x       - we multiply both sides of the equation by x
2.9511=2.5*x       - we divide both sides of the equation by (2.5) to get x
2.9511/2.5=x
1.18044=x
x=1.18044

now we have:
40% of 2.9511=1.18044
