1. I think these are all the possibilities, listed here in form a/b divided by c/d, but where a and d can be switched and/or b and c can be switched:

5/2 divided by 4/6 = 30/8
5/2 divided by 3/8 = 40/6 [as above]
7/2 divided by 4/9 = 63/8

2. Would this a possible solution also? Or would it be invalid?

9/3 divided by 1/6 equals 72/4

• I think 9/3 divided by 1/6 would be 72/3. I think it might be cool to have a class of solutions like this, where there is 1 repeated digit. In this case, the 1.

• 9/3 divided by 1/6 would actually be 54/3 so it wouldn’t work since the “3” is repeated.

• “9/3 divided by 1/6 equals 72/4” was original query

9/3 divided by 1/6 reduces to 54/3 hence 18
72/4 reduces to 18

Hence 18=18

I suppose the question is of repeats in original equation or no repeats in all the equations as you simplify and reduce.

3. My student found this solution:
9/2 divided by 4/7 equals 63/8

4. 5/4 divided by 2/6 = 30/8

5/3 divided by 2/8 = 40/6

7/2 divided by 4/9 = 63/8

9/4 divided 2/7 = 63/8
