Integer Subtraction; Range (-99) to (+99) (D) 3rd Column

Question 1:

(-29) - (-74) = 45
(-29) - (-74) = (-29) + (+74)

Question 2:

(+25) - (+39) = -14
(+25) - (+39) = (+25) + (-39)










Question 3:
(-70) - (+31)= -101
(-70) - (+31)= (-70) + (-31)

• 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.
