Answer:

• Group the h terms by organised term arrangement :

• Then using distributive property, factorise out the value h so that the reverse is true.

• for the variable "lw", divide it by h in order to add it to the bracket of (w + l). Make sure the reverse is true:

• finally, completely factorise out the value h

5/6
as there 6 outcomes and five of them (1,2,3,4,6) are divisors of 12
