149.99 is what percent of 219.99 - 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 219.99 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 219.99, so we can write it down as 100%=219.99.
4. We know, that x% equals 149.99 of the output value, so we can write it down as x%=149.99.
5. Now we have two simple equations:
1) 100%=219.99
2) x%=149.99
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%=219.99/149.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 149.99 is what percent of 219.99

100%/x%=219.99/149.99
(100/x)*x=(219.99/149.99)*x       - we multiply both sides of the equation by x
100=1.466697779852*x       - we divide both sides of the equation by (1.466697779852) to get x
100/1.466697779852=x
68.180371835083=x
x=68.180371835083

now we have:
