`4(1)/(2)times b(2)/(3)=7`

Show ((-8)/(7))times[(1)/(2)times((-4)/(3))]=[((-8)/(7))times(1)/(2)]times((-4)/(3))

[((-2)/(-3))times(1)/(5)]times((-2)/(7))=((-2)/(-3))times[(1)/(5)times((-2)/(7))]

Show that (4)/(7)times((-2)/(8)+(3)/(4))=(4)/(7)times(-2)/(8)+(4)/(7)times(3)/(4)

((-4)/(3))times(1)/(2)+((-4)/(3))times((-7)/(5))

If 1(2)/(3)+ ( 2)/( 7 ) xx ( x)/( 7) = 1( 1)/( 4) xx ( 2)/( 3) +( 1)/( 6) then find the value of x.

The value of (5 (1)/(9) - 7 (7)/(8)div9 (9)/(20)) xx (9)/(11)- (5(1)/(4) div (3)/(7) " of " (1)/(4) xx (2)/(7)) div 4 (2)/(3) + 1 (3)/(4) is (a) 2(1)/(4) (b) 2(1)/(3) (c) 3(1)/(4) (d) 4(1)/(2)

Evaluate : (-6/7)^2 times (2/3)^3 times (-7/4) times 3/2

Find the products given below and in each case verify the result for a=1,b=2 and c=3: ((-4)/(7)a^(2)b)xx((-2)/(3)b^(2)c) xx((-7)/(6)c^(2)a)
