Question 1186445
<br>
The response from one tutor shows the answer without saying anything about how to find the answer; presumably they just used trial and error.  Trial and error is sometimes useful in mathematics; but showing a solution obtained by trial and error doesn't teach the student anything.<br>
The other tutor, apparently thinking trial and error is the only method for solving the problem, simply says this is not a math problem.<br>
But there is, in fact, a simple formal mathematical method for solving the problem.<br>
If one of the five numbers is the product of the other four, then the product of all five of them is the square of that one number.<br>
(-2)(3/4)(1/6)(-1/4)(9) = 9/16 = (3/4)^2<br>
ANSWER: 3/4 is the product of the other four numbers.<br>
