Question

You need to cut 7 planks of wood that are 2 2/5 feet long each, and 4 planks of wood that are 2 3/4 each. If these are cut from a 27 ft length of wood, how much wood will be left ?

Answer 1

There would not be enough wood to make all of those cuts

Answer 2

2 2/5 x 7 = 16 4/5

2 3/4 x 4 = 11

16 4/5 + 11 = 27 4/5

there is no wood left because 27 4/5 is greater than 27. there is not enough wood to make all of these cuts.
