155 is what percent of 1423 - 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 1423 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 100% equals 1423, so we can write it down as 100%=1423.
4. We know, that x% equals 155 of the output value, so we can write it down as x%=155.
5. Now we have two simple equations:
1) 100%=1423
2) x%=155
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:
100%/x%=1423/155
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 155 is what percent of 1423

100%/x%=1423/155
(100/x)*x=(1423/155)*x       - we multiply both sides of the equation by x
100=9.1806451612903*x       - we divide both sides of the equation by (9.1806451612903) to get x
100/9.1806451612903=x
10.892480674631=x
x=10.892480674631

now we have:
155 is 10.892480674631% of 1423
