Answer:
1 5/8 days
Step-by-step explanation:
Days spent on English : 5 3/8 = 27/8 days
Days spent on science: 3 1/4 = 13/4 days
Days spent on math 1 1/2 = 3/2 days
Days spent on English and math = 27/8 + 3/2 = 27/8 + 12/8 = 39/8 days
Difference between English+math and science: 39/8 - 13/4
= 39/8 - 26/8 = 13/8 or 1 5/8 days
Tim's wrapping paper
15 - (4 1/3 + 5 3/8)
= 15 - (13/3 + 43/8)
= 360/24 - (104/24 + 129/24)
= (360 - 233)/24
= 127/24
= 5 7/24 feet
