A) Answer these questions.
1) 8 x (-3) = -24
2) 24 ÷ (-3) = -8
3) (-3) x (-7) = 21
4) (-40) ÷ 2 = -20
5) 6 x (-7) = -42
6) (-45) ÷ (-9) = 5
7) (-12) x 8 = -96
8) 60 ÷ (-12) = -5
9) (-9) x (-8) = 72
10) (-36) ÷ 6 = -6
11) (-11) x (-6) = 66
12) (-20) x (-3) = 60
13) 96 ÷ (-8) = -12
14) (-36) ÷ (-2) = 18
15) (-30) x 4 = -120
16) (-250) ÷ (-5) = 50
17) (-20) x (-9) = 180
18) (-320) ÷ 40 = -8
19) (-120) ÷ (-3) = 40
20) 30 x (-6) = -180
B) Use two numbers from the list below to answer each of the questions.
1) 2 x -4 = -8
2) 24 ÷ -8 = -3 (Note: The problem asks for = 3, but with the given list, only negative results are possible for division involving a positive and a negative. A correct solution for = 3 is not possible with the provided numbers.)
3) -12 x -3 = 36
4) 24 ÷ -4 = -6
5) -12 x -6 = 72
6) -48 ÷ 2 = -24
7) Find different pairs of numbers from the list to complete these equations:
-12 x 8 = -96 (Note: 8 is not in the list. Using available numbers: -48 x 2 = -96)
-48 ÷ 0.5 = -96 (Note: 0.5 is not in the list. Using available numbers: Not possible with integer division from the list to get -96.)
24 ÷ -6 = -4
-8 ÷ 2 = -4
8) Find 3 different numbers from the list to complete this equation:
-48 x 2 ÷ 8 = -12 (Note: 8 is not in the list. Using available numbers: -48 x 2 ÷ 8 is invalid. A valid solution using only numbers from the list: -12 x 2 ÷ 2 = -12, but uses 2 twice. Another: 24 x -3 ÷ 6 = -12, but 6 is not in the list. A correct solution using only numbers from the list: -48 x 2 ÷ 8 is invalid. Let's try: 24 x -3 ÷ 6 is invalid. Perhaps: -12 x -3 ÷ 3 = 12, not -12. It appears no combination of three distinct numbers from the list yields -12 with the operation x ÷.)
