Rain's Fraction Scribepost

When you're dividing fractions, you're seeing how many groups of what go into what.
Or how many equal pieces of chocolate are shared among a certain amount of people.
Here are some examples:

10 divided by 5, or 10 groups of five = 2

How many 5s go into 10? Or how many equal parts of 10 can be shared among 5 people?














A quick trick is to divide the first fraction by the second fraction, but flipped over; the reciprocal of the second fraction.














Here is a video about how to divide fractions.


And here is a fun fraction game.

My Test Corrections
I actually got the very first question incorrect, but that's because I wasn't careful to write the right number for the question.

That's what I did.



What I should have done was this:





Then I got the question about how many bits equal 16 bytes?
I did a series of tedious multiplying and dividing all for nothing because I didn't even read the question right. So this is what I should have done:





Because each bit is 1/8 of a byte. And I had to find out how many bits were in 16 bytes.

And lastly I didn't get wording the first of the three bottom questions right.
I said "How many groups of 5/6 are in 1/2?" but that's a division type question. What I should have wrote was "What is 1/2 groups of 5/6?" to make it a multiplying question.

That is all.

  4. Awesome post! Your post was very easy to understand since you highlighted the important words. I also liked how you explained the question by using a picture and you also filled them in with different colours which makes your post look interesting. You also used Mahalo which makes great YouTube videos on how to do stuff and also explains them with detail.
