• do you like rice noodle(pho) comment down below
• I ate it today
• Can we use fractions to anwser this question?
(like 3÷0.75 is equal to 3÷3/4,and that equals to 3x4/3.then we mark off the 3s ,so the anwser is 4.)
is doing it like that ok?
• I think that works because you're getting the same answer. To me it doesn't matter how you do it as long as you get the right answer.
• - [Instructor] In this video, we're going to see
if we can compute what three divided by 0.75 is equal to,
and I'll give you a little bit of a hint
before I tell you to pause the video.
So let's imagine three wholes right over here,
and what if we were to think of these three wholes,
these three ones, and what if we were to
think about them in terms of hundredths?
Well then we could, once we express these as hundredths,
we could say, well how many groups of 75 hundredths
