What is the ratio of contractual obligations that expire in less than 1 year to the ones that expire in 3-5 years?
{"Operating lease obligations": {"Less than 1 year": 1699, "1-3 years": 3950, "3-5 years": 2707, "More than 5 years": 36, "Total": 8392}, "Other borrowings": {"Less than 1 year": 131, "1-3 years": 145, "3-5 years": 219, "More than 5 years": 61, "Total": 556}, "Total": {"Less than 1 year": 1830, "1-3 years": 4095, "3-5 years": 2926, "More than 5 years": 97, "Total": 8948}}
less_than_1_year = df["Total"]["Less than 1 year"]
between_3_5_years = df["Total"]["3-5 years"]
answer = less_than_1_year / between_3_5_years
