143.99 is what percent of 179.99 - 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 179.99 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 179.99, so we can write it down as 100%=179.99.
4. We know, that x% equals 143.99 of the output value, so we can write it down as x%=143.99.
5. Now we have two simple equations:
1) 100%=179.99
2) x%=143.99
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:
100%/x%=179.99/143.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 143.99 is what percent of 179.99

100%/x%=179.99/143.99
(100/x)*x=(179.99/143.99)*x       - we multiply both sides of the equation by x
100=1.2500173623168*x       - we divide both sides of the equation by (1.2500173623168) to get x
100/1.2500173623168=x
79.998888827157=x
x=79.998888827157

now we have:
