Answer:
#4: 130/60, simplified is 13/6 (divide numerator and denominator by 10)
#5: 110/130, simplified is 11/13 (divide numerator and denominator by 10)
#6: 5/12
#7: 4/12, simplified is 1/3 (divide numerator and denominator by 4)
#8: 12/4, simplified is 3, or 3/1 (divide numerator and denominator by 4)
Explanation:
#4: Part 1 is 60 miles, and the whole trip is 60 + 20 + 50 = 130 miles
So while #1 was 60 over 130 for "60 to 130", now we'll put the 130 on top of the 60 for "130 to 60" as a spoken ratio
#5: I think they mean add part 1 to part 3, then compare to the whole.
so 60 + 50 = 110, and your answer is 110/130

Punch: 3 pints Hawaiian punch, 4 pints of orange juice, 5 pints of ginger ale is the recipe. When you pour that all together, you have 3 + 4 + 5 pints of mixed punch as a total, or 12 pints.
#6: 5 pints of ginger ale to 12 pints of punch: 5/12
#7: 4 pints of orange juice to 12 pints of punch: 4/12
#8 12 pints of the whole drink to 4 pints of orange juice: 12/4
