1/5 of bees flew to a cherry tree, 1/3 flew to a clover tree, and 3 times the difference of these 2 numbers buzzed over to a stand of heather. 3 flew around the hive circling and protecting the bee community. The question is, how many bees were there altogether?

**MathMate**, Tuesday, August 23, 2011 at 9:38pmFirst add up the fractions:

1/5 cherry tree

1/3 clover tree

difference = 1/3-1/5=(5-3)/15=2/15

3 times the difference = 2*3/15=2/5

What's left

=1-(1/5+1/3+2/5)

=(15-(3+5+6))/15

=1/15

So 3 bees equal 1/15 of the (small)colony.

Therefore

3*15 equal 15/15=whole colony.
