Tell which property allows you to compare `(2)/(3) xx [(3)/(4) xx (5)/(7)] and [(2)/(3)xx(5)/(7)] xx (3)/(4)`

Tell which property allows you to compute (1)/(5)xx[(5)/(6) xx (7)/(9)] as [(1)/(5) xx (5)/(6)]xx(7)/(9)

Tell what property allows you to compute (1)/(3)xx(6xx(4)/(5)) as ((1)/(3)xx6)xx(4)/(3)

Using appropriate properties, find (2)/(3)xx (-5)/(7) +(7)/(3) +(2)/(3) xx (-2)/(7) .

Verify that: (2)/(3)xx(-(4)/(5)+(-(3)/(7)))=(2)/(3)xx(-(4)/(5))+(2)/(3)xx(-(3)/(7))

(3/2 xx (-7)/4) - ((-5)/2 xx 3/4)

3-(1)/(2)of(4)/(7)+(5)/(7)xx(14)/(35)=

LCM of ( 2^(3) xx 3 xx5) and ( 2^(4) xx 5xx 7) is

(1/4 xx 2/7)- ( 5/(14) xx 2/3)

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))
