Melvin's fraction scribe post

 In class we learned more on dividing fractions. The first thing we did was looking over our homework that I will talk about later.When a whole number is being divided by a fraction you can not use the sharing  technique.When dividing whole numbers with fractions first turn the whole number into a fraction by making it a improper fraction by making it over 1 for ex. 4 divide by 1/4, 4/1 divided by 1/4.When we use a number line you have to make the denominator the same and keep adding the which fraction you have on each tick. For example if you have 12 divided by 6 you could rephrase it by making it how many groups of 6 go into 12 equally.Also we learned about the term reciprocal which means the fraction that is multiplied that creates a product of 1 for example: 1/8x 8/1= 8/8 = 1. Dividing fractions is basically the same as multiplying the fraction by its reciprocal.
The homework for today is:
7 divided by 1/3 ----l
9 divided by 1/5       l
10 divided by 3/4     l------------ needs to be shown in two
1/4 divided by 2       l                   different ways of writing.Only answer
2/3 divided by 4       l                   it once guys.
12 divided by 2/3     l
8 divided by 2/5 -----

here's a video that should help

some more explanations that are much more clear

 Fraction test corrections

In this question I didn't put the question in a different way
5/6= 5/12 
the question is : 5/6 x 1/2
The way to say the question  is : 5/6 groups of 1/2


5/8 divided  by 1/4 =  
 I put 2 and 1/4 when the real answer is
5/8= 5/8         
1/4= 2/8 6
How many times does 2/8 go into 5/8 equally?
2/8 go into 5/8, 2 and 1/8 times.
I also my work on the back of the paper was a bit messy and was unreadable so for 1/4 divided by 1/3 I put 3/4 and this is how I got my answer.

4,8, 12             12 is the common denominator
3,6,9,12


1/4 = 3/12  and 1/3 = 4/12
and 4/12 goes into 3/12 , 3/4 times

  1. Good Explanation! But you should add a pictorial representation on dividing fractions. And instead of making the video a link why not embed the video and make a link. But first learn how to make a correct link.
