🎃Happy Halloween! 👻

Somewhere out there, a math teacher just fainted… 😱💀

When simplifying fractions, you’re supposed to find common factors and get rid of those — not just the digits themselves!

Here are some spooky exceptions:

163/326 = 1/2 ✅

163 / 2×163

(cancel the 3’s and 6’s — and it still works!🫨)

16/64 = 1/4 ✅

4×4 / 4×4×4

(cancel the 6’s — spooky, right?💀)

49/98 = 1/2 ✅

7×7 / 2×7×7

(cancel the 9’s — somehow correct!👻)

Yes, students sometimes cancel digits instead of factors, and these rare examples actually work! It’s spooky, silly, and a great reminder that math can be full of surprises.

Challenge: 

Can you find more 2- or 3-digit numbers where digit cancellation still gives the right value?
