One and a half multiplied by 40 equals what?
We could use partitioning to help us answer this question. First, we can multiply one by 40 and then multiply a half by 40. One times 40 is 40. Half of 40 is 20.
Now what we need to do is add both parts together. 40 plus 20 is 60. One and a half multiplied by 40 equals 60.
