What is 2.99 percent of 3990 - 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 3990 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 3990 is 100%, so we can write it down as 3990=100%.
4. We know, that x is 2.99% of the output value, so we can write it down as x=2.99%.
5. Now we have two simple equations:
1) 3990=100%
2) x=2.99%
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:
3990/x=100%/2.99%
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 2.99% of 3990

3990/x=100/2.99
(3990/x)*x=(100/2.99)*x       - we multiply both sides of the equation by x
3990=33.444816053512*x       - we divide both sides of the equation by (33.444816053512) to get x
3990/33.444816053512=x
119.301=x
x=119.301

now we have:
2.99% of 3990=119.301
