Question

rewrite k is less than 12 using >,

Answer 1

This is fairly simple 12>k(12 is more than k) or k<12(k is less than 12)

Answer 2

k is less than 12, so if you put k first, it would be written as k < 12.
However, you are needing to use >.
Therefore the answer is
12 > k (This says that 12 is greater than k, but it can also be said as k is less than 12, if read backwards)
