(1) Tucker painted 2/3 of his deck before lunch so he has 1/3 of the deck to paint after lunch.(1 - 2/3). So you do 1/3 of of the deck (76 1/2 meters square) to paint. 1/3 x 76 1/2 is 25 1/2 meters square. 25 1/2 is 25.5.
(2) This is like the last problem just with different numbers. She has 3/5 of 2 1/2 hours left. So you times 3/5 by 2 1/2. You get 1 1/12 which is 1.5.
