Question

Multiply the sets of numbers and match them with their products

Answer 1

(-
`(3)/(4))((7)/(8)) =-(21)/(32)`

(
`(5)/(16))(-2)(-4)(-(4)/(5)) = -2`

`((2)/(3))(-4)(9) = -24`

`(2(3)/(5))((7)/(9)) = (91)/(45)`

Answer 2

1. -21/32

2. -24

3. -2

4.
`(91)/(45)`

Explanation:

(1)
`((-3)/(4))((7)/(8))=-((3)/(4))((7)/(8))`

`=-((3*7)/(4*8))=-((21)/(32))`

(2)
`((2)/(3))(-4)(9)=((2)/(3))((-4)/(1))((9)/(1))`

=-
`((2*4*9)/(3*1*1))=-((72)/(3))`

= -24

(3)
`((5)/(16))` (-2) (-4)
`((-4)/(5))`

=
`((5)/(16))(+8)((-4)/(5))`

= -
`((5*8*4)/(16*1*5))=((160)/(80))`

= -2

(4)
`(2(3)/(5))((7)/(9))=((13)/(5))((7)/(9))`

=
`((91)/(45))`
