What fraction goes in the box to make it correct?
7
×
□
=
1

Step-by-step explanation:

The product of a number and its reciprocal = 1 , that is

n × = 1 , then

7 × = 1

(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
