194.5 is what percent of 220 - 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 220 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 220, so we can write it down as 100%=220.
4. We know, that x% equals 194.5 of the output value, so we can write it down as x%=194.5.
5. Now we have two simple equations:
1) 100%=220
2) x%=194.5
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%=220/194.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 194.5 is what percent of 220

100%/x%=220/194.5
(100/x)*x=(220/194.5)*x       - we multiply both sides of the equation by x
100=1.1311053984576*x       - we divide both sides of the equation by (1.1311053984576) to get x
100/1.1311053984576=x
88.409090909091=x
x=88.409090909091

now we have:
194.5 is 88.409090909091% of 220
