2/5 × [(-3/7)-(1/6×3/2) + (1/4 × 2/5) ]
= 2/5 × [(-3/7)-(3/12)+(2/20)]
= 2/5 × [(-3/7)-(1/4)+(1/10)]
=2/5 × ( -60 - 30 + 12 )/120
= 2/5 × (-60-18)/120
= 2/5 × (-78)/120
= -156/600
=-13/50
= 2/5 × [(-3/7)-(3/12)+(2/20)]
= 2/5 × [(-3/7)-(1/4)+(1/10)]
=2/5 × ( -60 - 30 + 12 )/120
= 2/5 × (-60-18)/120
= 2/5 × (-78)/120
= -156/600
