division problems?

Question

(2/3) ÷ (-4/9)

(-5/6) ÷ (-10/3)

(-9) ÷ 3

9 ÷ (-3)

(-9) ÷ (-3)

Answer 1

note:
to divide fractions you invert and multiply

2/3 ÷ -4/9 = 2/3(-9/4)
cross cancel
= -3/2

-5/6 ÷ -10/3 = -5/6(-3/10)
negative * negative = positive
cross cancel
= 1/4

9 ÷ - 3 = -3

-9 ÷ -3 = +3

Answer 2

When you divide by a fraction, "flip" the second fraction and then multiply:

so 2/3 divided by -4/9 is

2/3 X -9/4 = -18/12, which reduces to -1 1/2

(when multiplying a + and a -, the answer will always be -. Remember, if the signs are the same, the answer is positive, if different, negative.)

Next:
-5/6 x -3/10 = 1/4 (2 negatives = +)

-9/3 = -3

9/-3 = -3

but -9/-3 = 3 (same signs make the answer positive.

Answer 3

(2/3) ÷ (- 4/9) =

Remove parenthesis

2/3 ÷ - 4/9

2/3 x - 9/4 =

- 18/12 =

- 3/2

- - - - - - - -

(- 5/6) ÷ (- 10/3) =

Remove parenthesis

- 5/6 ÷ - 10/3 =

- 5/6 x - 3/10 =

15/60 =

1/4

- - - - -

division of a positive and negative numbes results in the quotient being negative ( - )

(- 9) ÷ 3

is the same as

- 9 / 3 = - 3

- - - - - - -

9 ÷ ( - 3)

remove parenthesis

9 ÷ - 3 = - 3

is the same as

9 / - 3 = - 3

- - - - - - - -

Division of negative numbers results in the quotient being positive (+)

(- 9) ÷ ( - 3) =

Remove parenthesis

- 9 ÷ - 3 = 3

is sthe same as

- 9 / - 3 = 3

- - - - - - - - - -s-

Answer 4

(2/3) / (-4/9) =
(2/3) * (9/-4) =
18/-12 =
-3/2

(-5/6) / (-10/3) =
(-5/6) * (3/-10) =
(5 * 3)/(6 * 10) =
15/60 =
1/4

-9 / 3 = -3

9 / -3 = -3

-9 / -3 = 3

Answer 5

solving the 1st
(2/3)*(-9/4)
2*(-9)/3*4
-18/12
-9/6
-3/2
Similarly you can solve others

Answer 6

(2/3)(-4/9)=2/3-4/9=2/9
(-5/6)+(-10/3)=-5/6-10/3=-25/6.
(-9)+3=-6
9+(-3)=9-3=6.
(-9)+(-3)=--9-3=-12

Answer 7

1. -3/2

2. 1/4

3. -3

4. -3

5. 3
