Are There More Interesting Numbers Like This?

AI Thread Summary
The discussion centers on identifying interesting numerical relationships where fractions can be simplified by crossing out digits, specifically focusing on cases where the digits are different. Examples provided include 26/65 simplifying to 2/5 and 16/64 to 1/4, both achieved by removing the digit '6'. The conversation also explores whether there are any three-digit examples where two digits can be crossed out while maintaining a valid fraction. A program is shared that searches for such relationships, yielding results like 19/95 simplifying to 1/5 and 49/98 to 4/8. However, it concludes that no three-digit non-trivial cases exist for the specified conditions.

26/65 = 2/5 (cross out the sixes)

16/64 = 1/4 (again cross out the sixes)

are there anymore *interesting* numbers like this?

by interesting i mean that its not 11/11, since you can obviously cross out the 1's and get 1/1. the numbers have to be different

also, are there any 3 digit ones where you can cross out 2 of the digits? (etc, etc)

Program:
Code:
Private Sub Form_Load()
Dim x As Single
Dim z As Single
Dim y As Single
    For x = 1 To 1000
    For z = 1 To 1000
        If 10 * x / z <> 1 Then
            y = 9 * x / (10 * x / z - 1)
            If y = CLng(y) And y > 0 And (y <> x Or y <> z) Then
                If CSng(x & y) / CSng(y & z) = x / z Then
                    Debug.Print x & ", " & z & ", " & y & ": " & x & y & "/" & y & z & "=" & x & "/" & z
                End If
            End If
        End If
    Next z
    Next x
End Sub

Results:
1, 4, 6: 16/64=1/4
1, 5, 9: 19/95=1/5
2, 5, 6: 26/65=2/5
4, 8, 9: 49/98=4/8

There are no 3 digit non-trivial (x=y=z) cases (at least for x and z, possibly for y).
 
thanks a lot for all the help. :)
 
Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
