Use the distributivity of multiplication of rational numbers over their addition to simplify:
(i) `2/7xx(7/(16)-(21)/4)`
(ii) `3/4xx (8/9-40)`

Use the distributibity of multiplication of rational numbers over their addition to simplify: (2)/(7)x((7)/(16)-(21)/(4))( ii) (3)/(4)x((8)/(9)-40)

Use the distributibity of multiplication of rational numbers over their addition to simplify: (3)/(5)x((35)/(24)+(10)/(1))( ii) (-5)/(4)x((8)/(5)+(16)/(5))

Distributivity of multiplication over addition the multiplication of rational numbers is distributive over their addiction.

Simplify: (i) (7)(18) xx(-4) (ii) (-36) xx ((-5)(9))

Using commutativity and associativity of addition of rational numbers,express each of the following as a rational number: (2)/(5)+(7)/(3)+(-4)/(5)+(-1)/(3) (ii) (3)/(7)+(-4)/(9)+(-11)/(7)+(7)/(9)

Simplify: 3/4+7/(16)+5/8

Name the property of multiplication shown by each of the following statements: (i) (-12)/(5) xx (3)/(4)=(3)/(4)xx (-12)/(5) (ii) (-8)/(15) xx 1=(-8)/(15) (iii) ((-2)/(3) xx (7)/(8)) xx (-5)/(7) = (-2)/(3) xx ((7)/(8) xx (-5)/(7)) (iv) (-2)/(3) xx 0=0 (v) (2)/(5) xx ((-4)/(5) +(-3)/(10)) = ((2)/(5) xx (-4)/(5)) +((2)/(5)xx (-3)/(10))

Simplify: ((4)/(7)+(-8)/(9) +(-5)/(21) +(1)/(3)) .
