Today we learned a little more about dividing fractions.
Today we learned and used "Reciprocles" and we used the phrase "Share __ (Fraction) between __ (Whole Number) equal groups". I'll explain what they are and how they're used.
This a "Reciprocle".
I apologize if the picture is a little bit blurry.
A reciprocle is just flipping the fraction (1/4) upside down to multiply it and get 1.
Doesn't make sense? There's a part in the video below that talks about it.
You make the fraction in the denominator (Sorry, if this is confusing) a whole number and you do the same to the whole number on top. You'll get an answer over 1.
We also learned how to divide fractions by a whole number. To do this, you must think about "Sharing the fraction between a number of equal groups".
1/4 ÷ 6 =
The part we have is 1/4. Then we'll divide 1/4 into 6 equal groups. Just like this. And you can also use "Receptacles" just like this.
This is what we've learned in class today.
Also sorry if this is kind of a late post.

Have a Goodnight 8-14(: and sorry for the late post.
If this doesn't make sense, here's a video.
My first mistake was on 2 1/2 X 1 3/5.
I forgot to make both the fractions improper. 2 1/2 should've been 5/2 and 1 3/5 should've been 8/5. If I multiply 5/2 by 8/5, my answer would've been 40/10 or 4.
My second mistake was on 3/4 divided by 5/12.
I accidentally put 4 X 5 = 40 when it actually equals 20. (Stupid Mistake)
The answer to this question should've been 36/20 or 1 4/5.
My third mistake was on 2 1/4 X 1 1/3.
I made the same exact mistake here. I forgot to make both fractions improper.
2 1/4 should've been 9/4 and 1 1/3 should've been 4/3.
If I multiply 9/4 by 4/3, my answer should've been 36/12 or 3.
My fourth mistake was on the computer terminology question.
I confused myself on this question.
I put 8/8 X 16/1 which gives 96/8 or 12.
I then noticed that my mistake is that 12 represents the bytes. The question was how many bits equal 16 bytes. I left out the other 4 bytes. The correct answer should've been 128 because each byte contains equals 8 bits.
My fifth mistake was on the pie question.
I put 1/2 - 1/4 = 1/4. I also confused myself here too. I should've multiplied 1/2 by 1/4 which gives me 1/8.
My sixth mistake was on 1 1/2 divided by 1/4.
Here, I forgot to make 1 1/2 into an improper fraction which should've been 3/2.
The answer should've been 12/2 or 6.
My final mistake was on making 5/8 divided by 1/4 a picture.
This should have been the correct picture. This shows 2 1/2
