Any whole number equals itself over 1.
16/1 x 5/12
With multiplication, you work straight across.
(16 x 5)/(1 x 12) = 80/12
Can 80/12 be reduced? Both 80 and 12 are divisible by 4, so 80/12 = 20/3.
Do you need to convert it to an improper fraction? How many threes make 20? Six, with two left over.
6 2/3
