Julia has 14 butterfly stickers. Daria has 26 butterfly stickers. How many more butterfly stickers does Daria have than Julia?
Leno4ka [110]

Answer:

  • 12
  • B: additive comparison

Step-by-step explanation:

The word "more" in this context means we want to find the difference between the number Daria has and the number Julia has. It is an "additive" comparison.

You need to be a little careful with this. You will often see wording such as "... <em>times more</em> than ...", in which case it is a multiplicative comparison. (I would prefer the multiplicative comparison wording to be "... times as many as ...", so that "more" is reserved for additive comparisons. Alas, not in this lifetime.)
