Question

Martin decided to buy 2 bags of grapes weighing 5 and two-thirds pounds each, instead of the 3 bags weighing 4 and one-fifth pounds each, because the bigger bags were on sale. Did he end up with more grapes or less grapes by buying the bigger bags?
He ended up with about One-half pound less grapes.
He ended up with about One-half pound more grapes.
He ended up with about 1 pound less grapes.
He ended up with about 1 pound more grapes.

Answer 1

Less grapes.

2 × 5 2/3 = 2 × 17/3 = 34/3 ≈ 11.333 lb.
3 × 4 1/5 = 3 × 21/5 = 63/5 = 12.6 lb.
Difference = 12.6 − 11.333 = 19/15 ≈ 1.27 lb.

So he ended up with about 1 pound less grapes.
