Question

(1/2+1/3+1/4)[(1/2×1/3)+(1/3×1/4)+(1/4×1/2)]-(1/2×1/3×1/4)​

Answer 1

Answer:

(1/2+1/3+1/4)[(1/2×1/3)+(1/3×1/4)+(1/4×1/2)]-(1/2×1/3×1/4)

=> (1/2+1/3+1/4)[1/6+1/12+1/8]-(1/2×1/3×1/4)

=> (1/2+1/3+1/4)[(4+2+3)/24]-(1/2×1/3×1/4)

=> (1/2+1/3+1/4)[9/24]-(1/2×1/3×1/4)

=> (1/2+1/3+1/4)[3/8]-(1/2×1/3×1/4)

=> {(2+3+4)/12}[3/8]-{(2+3+4)/12}

=> {9/12}[3/8]-{9/12}

=> {3/4}[3/8]-{3/4}

=> 9/32-3/4

=> (9-24)/32

=> -15/32
