This maybe comes from the way we use the word “fraction” colloquially. As in “it took just a fraction of a second…” Perhaps you could bring this up, and emphasize the difference between the English meaning and the math meaning, providing examples like .00000000004 and 3/2. To be silly, you could substitute the word “decimal” for “fraction” when you talk about small things, which sounds ridiculous. “Only a decimal of the students missed question #4…”

8.3+7.7

Round to nearest whole number.

Mistake:

8 + 7 = 15

Correct:

8+8=16
