Question

If a = (4/5) , b = (5/7) and c = (3/8) , prove that i) a x (b – c) = (a x b) – (a x c)

Answer 1

Answer-

0.2714285714285

Step-by-step explanation:

a = 4/5

b = 5/7

c = 3/8

L.H.S a x (b-c)

= 4/5x(5/7-3/8)

= 4/5(40-21/56)

= 4/5x19/56

= 76/280

= 0.27142857

R.H.S (a x b) - ( a x c )

=( 4/5 x 5/7 ) - ( 4/5 x 3/8 )

= (4/7)-(12/40)

= 0.5714285714285 - 0.3

= 0.2714285714285

a x ( b - c) = ( a x b ) - ( a x c )

0.2714285714285 = 0.2714285714285

L.H.S = R.H.S ( prove )
