GPT-4: If 2 bebs are equal to 1 bib, and we know that 1 beb equals 2 bobs, we can determine how many bobs there are per bib using simple substitution.

GPT-4: If 2 bebs are equal to 1 bib, and we know that 1 beb equals 2 bobs, we can determine how many bobs there are per bib using simple substitution. 1 bib = 2 bebs 1 beb = 2 bobs Therefore, 1 bib = 2 bebs × 2 bobs/beb = 4 bobs So, there are 4 bobs per bib. Nitpick: A properly done substitution would've arrived at 1 bib = 2 × (2 bobs) without needing any of the "2 bebs × 2 bobs/beb" nonsense. It doesn't teach this task very well.
