What is 5000 percent of 1.8 - 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 1.8 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 1.8 is 100%, so we can write it down as 1.8=100%.
4. We know, that x is 5000% of the output value, so we can write it down as x=5000%.
5. Now we have two simple equations:
1) 1.8=100%
2) x=5000%
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:
1.8/x=100%/5000%
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 5000% of 1.8

1.8/x=100/5000
(1.8/x)*x=(100/5000)*x       - we multiply both sides of the equation by x
1.8=0.02*x       - we divide both sides of the equation by (0.02) to get x
1.8/0.02=x
90=x
x=90

now we have:
5000% of 1.8=90
