p=-8/27, q=3/4 and r=-12/15
L.H.S. = p×(q-r)
= -8/27×{3/4-(-12/15)}
= -8/27×{3/4+12/15}
= -8/27×(45+48/60)
= -8/27×93/60
= -0.45
R.H.S. = p×q-p×r
= (-8/27×3/4)-(-8/7×-12/15)
= 0.45
L.H.S. = p×(q-r)
= -8/27×{3/4-(-12/15)}
= -8/27×{3/4+12/15}
= -8/27×(45+48/60)
= -8/27×93/60
= -0.45
R.H.S. = p×q-p×r
= (-8/27×3/4)-(-8/7×-12/15)
= 0.45
