Whole numbers are: 0, 1, 2, 3, 4, 5, 6, … Integers are: …, -4, -3, -2, -1, 0, 1, 2, 3, 4, … Any integer that is a negative number, like -3 or -546, can not be a whole number.
1/6 of an hour= 10 because 60mins=1hour & 60/6=10 so the sailboat travels 2 1/2 miles in 10 mins. So the complex fraction would be 2 &1/2 over 10. Hope it helps!
