Question 1022594
For this question, you would have to put a number in to represent the variable or the missing number, let's say that Brad is 6 and Brad's dad is 4 times older than Brad, so you would have to multiply 6 and 4 together and that is 24.  In 4 years, Brad will be one-third of Brad's age, so that means that Brad would be 10 and the father would be 28.
