1.5 = 90 = 1:30 1.5 minutes = 90 seconds = 1 minute and 30 seconds Just 3 different ways to represent the same thing in math but without the accompanying qualifiers the math would be wrong. Probably other examples out there but that is the simplest that I can think of off the top of my head

Good Answers. My answer, A decimal, percentage and fraction are all different but the exact same thing, .5 = 50% = 1/2.
