mrs.dryson divided her collection of 52 glass bears into equal groups. she had one bear left over.how many groups did Mrs.dryson make how many bears are in each group

She had 1 bear left over.
That means she was able to divide 51 bears evenly.
51 can be divided by only 2 numbers (other than 1 and 51), NAMELY, 3 and 17, both of which are prime.

She either made 17 groups of 3 or 3 groups of 17.
Either way, she'd use 51 bears and have 1 left over.
