To divide 3/8 ÷ 1/4 using a model, which of the following are true? Select all that are correct.

alina1380 [7]

So your answer according to these hints I provided for you, should lead you to your answer, which should in other words be,

The 1st. The 2nd. And I would say...The 4th. The reason why I say not the 3rd one is because the 4 has nothing to do with the 8, the 3 does because it's divided by it.

If it's not useful, feel free to report for mistake in answer. -_-
