What is 645 percent of 1.5 - 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 1.5 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 1.5 is 100%, so we can write it down as 1.5=100%.
4. We know, that x is 645% of the output value, so we can write it down as x=645%.
5. Now we have two simple equations:
1) 1.5=100%
2) x=645%
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:
1.5/x=100%/645%
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 645% of 1.5

1.5/x=100/645
(1.5/x)*x=(100/645)*x       - we multiply both sides of the equation by x
1.5=0.15503875968992*x       - we divide both sides of the equation by (0.15503875968992) to get x
1.5/0.15503875968992=x
9.675=x
x=9.675

now we have:
645% of 1.5=9.675
