What is 3.3 percent of 42.9 - 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 42.9 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 42.9 is 100%, so we can write it down as 42.9=100%.
4. We know, that x is 3.3% of the output value, so we can write it down as x=3.3%.
5. Now we have two simple equations:
1) 42.9=100%
2) x=3.3%
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:
42.9/x=100%/3.3%
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 3.3% of 42.9

42.9/x=100/3.3
(42.9/x)*x=(100/3.3)*x       - we multiply both sides of the equation by x
42.9=30.30303030303*x       - we divide both sides of the equation by (30.30303030303) to get x
42.9/30.30303030303=x
1.4157=x
x=1.4157

now we have:
3.3% of 42.9=1.4157
