Hint: ratio = divide(max(value where indicatorname = 'Number of infant deaths' and year = '1971'), min(value where indicatorname = 'Number of infant deaths' and year = '1971')); the highest number of infant deaths in 1971 refers to max(value where indicatorname = 'Number of infant deaths' and year = '1971'); the lowest number of infant deaths in 1971 refers to min(value where indicatorname = 'Number of infant deaths' and year = '1971')

Question: What is the ratio between country with the highest number of infant deaths in 1971 and the lowest number of infant deaths in 1971? List the country with the highest number of infant deaths in 1971 and the lowest number of infant deaths in 1971.

assistant: SELECT CAST(MAX(value) AS REAL) / MIN(value) FROM indicators WHERE indicatorname = 'Number of infant deaths' AND year = '1971' UNION ALL SELECT countryname FROM ( SELECT countryname, MAX(value) FROM indicators WHERE indicatorname = 'Number of infant deaths' AND year = '1971' ) UNION SELECT countryname FROM ( SELECT countryname, MIN(value) FROM indicators WHERE indicatorname = 'Number of infant deaths' AND year = '1971' )
