### Pamela's Fraction Scribepost

Math Textbook: Page 227-229. Number 2, 5, and 7.

2. No, because the proper way to do it is....

• Times the denominator by 3/2.
• Flip 2/3, and you have a reciprocal of 3/2.
• Times the numerator by 3/2
• The answer is 9/8, simplify it (1 1/8)

5. a) 5/8 ÷ 1/4=

•  Q: How many groups of 1/4 are in 5/8?
•  Estimate: <1    >1
• Then you do the math.
• Then you draw a diagram.

b)1/4 ÷ 1/3=

•  Q: How many groups of 1/3 are in 1/4?
•  Estimate: <1    >1
• Then you do the math.
• Then you draw a diagram.

c) 1 1/2 ÷ 2/3=

•  Q: How many groups of 2/3 are in 1 1/2?
•  Estimate: <1    >1
• Then you do the math.
• Then you draw a diagram

d)2 1/3 ÷ 5/6=

• Q: How many groups of 5/6 are in 2 1/3?
•  Estimate: <1   >1
• Then you do the math.
• Then you draw a diagram

7. a) 3/5 ÷ 9/10=

• You find the common denominator.
• 3/5 and 9/10 the common denominator is 10.

b) 1 1/2 ÷ 5/6=

• You find the common denominator.
• 1 1/2 and 5/6 the common denominator is 6.

c) 3 1/3 ÷ 1 5/6 =
• You find the common denominator.
• 3 1/3 and 1 5/6 the common denominator is 6.

Math Test Corrections

In a computer terminology, a bit is 1/8 of a byte. How many bits equal 16 bytes?

Tamar had 1/2 of an apple pie in her refrigerator. She ate 1/4 of this piece of pie. What fraction of a whole pie did she eat?

5/6 x 1/2 = 5/2
1/4  ÷ 1/3 = 3/4

5/8  ÷ 1/4= 2 1/2

1. Very nice. I like how you took your time to organize and take pictures to make others learn and understand more about it.

2. Very Orginized and It was easy to understand GOODJOB PAM <3

3. Good Job Pamela! I liked how you took pictures of your own work! It looks very clear and understanding. Good Job!

4. Nice clean organized good info very helpful love the guy in the video

5. Your post was very neat, and organized, You had a lot of pictures of what you did, a link to something good, a video to help understand fractions more and you had words, I also like how you estimated, and wrote what the question is asking in words. You should also include the questions, so that we know what question it is that you are asking.
good Job!
