\\ \tt \longmapsto 2 (1)/(3) / 4(1)/(3) = (7)/(x) \\ \\ \tt \longmapsto (7)/(3) / (13)/(3) = (7)/(x) \\ \\ \tt \longmapsto (7)/(3) * (3)/(13) = (7)/(x) \\ \\ \tt \longmapsto (7)/(13) = (7)/(x) \\ \\ \tt \longmapsto 7x = 7 * 13 \\ \\ \tt \longmapsto 7x = 91 \\ \\ \tt \longmapsto x = (91)/(7) \\ \\ \tt \longmapsto x = 13

Answer:


x = 13

Explanation:


(2 (1)/(3) )/(4 (1)/(3) ) = (7)/(x) \\ (7)/(3) / (13)/(3) = (7)/(x) \\ (7)/( 3) * (3)/(13) = (7)/(x) \\ (7)/(13) = (7)/(x) \\ 7x = 13 * 7 \\ x = (13 * 7)/(7) \\ x = 13
