I have classmates who read the following equation in the following way:

3x(1-1/0.1) as three into one minus 1 over 0.1 but I don't know if this into is used because I have "(" or because I have "x"

No. "Into" always means "divided by." It never means "times."

Give your classmates an F.

Where are those classmates of yours from?
Maybe they use "into" because of the distributive propriety of multiplication towards sum, regarding reals. (I mean probably they do that because of the "(" instead of the "x")

Perhaps some kind of "international English" is in use here, regarding math?

That is what I suspected. Such usage is probably associated to the distributivity of multiplication toward addition.
