@@robertakerman3570 Every rational number a/b where a and b are natural numbers does have a repeating group of values, easy to proof. If a decimal has a repeating group it is easy to proof that that number is a rational number, a fraction. So is a number is irrational like pi or e or⎷2 it can't have a repeating group. Se also my comment about the video for another remark.
Why not mentioned that the repeating group does not have to start immediately after the decimal point? The way you present the information may suggest that for a lot of students. And that implies that a lot of students will look for the repetition including the first decimal after the point.) Try to make the examples as general as possible and do not use special cases where the repeating starts immediately after the decimal point. Counter example: 431 / 700. = 0.61571428571428571428...... (repeating group 574128. but befor that group we have the decimals 61)
THANKS a lot
We can say "to the best of Our knowledge" this # does not repeat. Prolly correct, but no one can say 4 sure.

Interesting way of teaching. I might actually use one of your methods when I teach my learners. I like. 🌱
But see my remark!
Amazing videos!

Thank you so much.

Ooh
