What is 150 percent of 423 - 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 423 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 423 is 100%, so we can write it down as 423=100%.
4. We know, that x is 150% of the output value, so we can write it down as x=150%.
5. Now we have two simple equations:
1) 423=100%
2) x=150%
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:
423/x=100%/150%
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 150% of 423

423/x=100/150
(423/x)*x=(100/150)*x       - we multiply both sides of the equation by x
423=0.66666666666667*x       - we divide both sides of the equation by (0.66666666666667) to get x
423/0.66666666666667=x
634.5=x
x=634.5

now we have:
150% of 423=634.5
