Question

Questions 2-5. Simplify each of the following.

2. (-1/3)(12)(-3/4)
3. 1/4(-8a + 4b)
4. (24x - 12y)(-1/6)
5. 1/2(4c - 6d) - 1/3(6c-9d)​

Answer 1

2. (-1/3)12 => -12/3 => -4
-4(-3/4) => 12/4 => 3

3. 1/4(-8a)=> -8a/4 => -2a

1/4(4b)=> 4b/4 => b

-2a+b

4. -1/6(24x) => 24x/-6 => -4x

-1/6(-12y) => -12y/-6 => 2y

2y-4x


5. 1/2(4c-6d)

1/2(4c)=> 4c/2 => 2c
1/2(-6d)=> -6d/2 => -3d

-3d+2c….

-1/3(6c-9d)
-1/3(6c)=> 6c/-3 => -2c

-1/3(-9d)=> -9d/-3 => 3d

3d-2c


going back to the first part and adding everything together:

-3d+2c+3d-2c=0
