Question

Mr. Fried plans to give fruit flies to 6 groups of lab students for an experiment. He wants to give the same number of flies to each group. He has different size bottles. How can Mr. Fried give each group the same number of fruit flies without opening the bottles?

2 large bottles: 12 fruit flies in each bottle
10 medium bottles: 8 fruit flies in each bottle
14 small bottles: 2 fruit flies in each bottle

Answer 1

He has 24+80+28 total flies, divided by six grups, is 132/6=22 flies each.

how can we get 22
1 large bottle, 1med, plus 1small (guve those to two groups)
Now we have four groups left, no large, 8 med, and 12 small left.
give 2 med, plus 3 small to 4 groups
he is now out of large, out of med, and no small left. Poor Mr Feied
