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.

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
