Answer:
No. See below.
Step-by-step explanation:
I've never heard anyone say this out loud. However, on Brainly, it is always interpreted as 1 1/2 = 1.5. So it is 1 plus 1/2.
1 to 2 is a ratio. For every set of car keys I have 2 house keys.
1 to 2 can be written either as 1/2 or 1:2 depending on how touchy your instructor is.
So no. 1 1/2 is not the same as 1:2
