Which expression simplifies to -2/5 ?

A. -(1/2)×(-5/4)

B. -(1/2)×(-4/5)

C. -(-1/2)×(-5/4)

D. -(-1/2)×(-4/5)

D)-(-1/2)×(-4/5)

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

eve and marks ratios are equivalent
