Question

IN THE LAST TWO WEEKS , A PLANT GREW 1/16 IN. AND 3/16 IN. RESPECTIVELY

Answer 1

I'm assuming you mean that the plant grew 1/16th of an inch the first week, and 3/16th of an inch the next week. Simply add the two together (4/16th) and simplify. Since four goes into both numbers, the simplified version is 1/4th. Hope this helps
