Question: how do u write 20 as a fraction?
Answer: “20” per se can be written as a fraction as n/1 = 20/1. Footnote: There are an infinite number of rational numbers that are equivalent to 20, e.g., 40/2, 80/4, 100/5, 120/6, 400/20, 1000/50, etc., but, again, to write 20 per se as a fraction is 20/1.
