Answer :
He would need to buy 5 bags:
2=(12/6) so:
(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)=60/6
(12/6)+(12/6)+(12/6)+(12/6)+(12/6)=60/6
2=(12/6) so:
(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)+(5/6)=60/6
(12/6)+(12/6)+(12/6)+(12/6)+(12/6)=60/6
Assuming that he doesn't have a few snacks then he would need to buy 5 bags of Peanuts. But how many bags does he wish to fill? The answer is extremely variable if that key element is forgotten.
