Question

Macs hotal had 128 rooms and 25% of the rooms in the hotel did not have an ocean view. Write an expression to find the total number of rooms in the hotel that had an ocean view.

Answer 1

water : cranberry :: 5 3/4 : 3 1/2

water : cranberry :: 23/4 : 7/2      convert to improper fractions

water: cranberry :: 23/14 : 1        divide both by 7/2

Answer 2

Total number of rooms:    128

Rooms without ocean view:    (25/100)*128 = 32 [that is, 25%]

Rooms with an ocean view:

    ( 1 - 25/100)*128    or   (75/100)*128    [that is, 75% of 128]
