For this case we are told that 60% of a number "x" is 22. Then, to find the number we make a rule of three:
x --------------> 100%
22 ------------> 60%
Now, we find 45% of the number "x" found:
36.67 --------> 100%
y ---------------> 45%
Where "y" represents the number that is 45% of x.
So, 15.50 is 45% of x
