2. Mike carried out the division 3/4 / 2/3 as follows.

3 2 4 2

--- / --- = --- x ---

4 3 3 3

8

= ---

9

Do you agree with Mike’s method and answer? Explain.

No, because he made a reciprocal on the first one. (in our method, the numerator)

5. a) 5/8 / 1/4 find a common denominator.

5/8 / 2/8 = 2 1/2

3/12 / 4/12 = 3/4

c) 1 1/2 / 2/3 find a common denominator

9/6 / 4/6 = 2 1/4

d) 2 1/3 / 5/6 find a common denominator

14/6 / 5/6 = 2 4/5

14/6 / 5/6 = 2 4/5

7. a) 3/5 / 9/10 = 6/10 / 9/10 = 2/3

find the common denominator

6 10 60 2

--- x --- = --- = ---

10 9 90 3

-------

9 10

--- x --- = 1

10 9

b) 1 1/2 / 5/6 = 9/6 / 5/6 = 1 4/5

find the common denominator

9 6 54 4

--- x --- = --- = 1 ---

6 5 30 5

-------

5 6

--- x --- = 1

6 5

c) 3 1/3 / 1 5/6 = 20/6 / 11/6 = 1 9/11

find the common denominator

I think you did a good job. I liked how you added a picture to explain your answers. I liked how you put a video too!

ReplyDeleteHEY JETHRO, GOOD JOB ON YOUR POST. THE PICTURES REALLY HELP ME UNDERSTAND FRACTIONS, BUT YOU NEED TO EXPLAIN MORE

ReplyDeleteGood Job Jethro! Your pictures really helped me understand on how to divide fractions! Next time, I suggest you explain more on how to get the answer. Overall, nicely done.

ReplyDeleteand the video you put really helped me!

ReplyDeleteGood job! I understood your explanation for it but you could have put some of the ones you solved on pictures so its easier to get. Other than that your other pictures were really easy to understand. The video you put was good too.

ReplyDeleteGood job! I like how you added pictures to explain your answers. I also like how you put a video to help us with math problems like these.

ReplyDeleteGood job, you put effort into this and shows, you had videos and pictures that really help, Good job.
