36 for 4 hats = 36/4 = 9 per hat 56 for 7 hats = 56/7 = 8 per hat not equivalent
12 posters for 36 students = 12/36 = 1/3 poster per student 21 posters for 63 students = 21/63 = 1/3 poster per student these are equivalent...although it does not make much sense...each person getting 1/3 of a poster. And if there was a mistake and it was supposed to be 36 posters for 12 students and 63 posters for 21 students...it would still be equivalent
