In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If 2/ 7 of the drink is apple juice and 1/ 2 is orange juice then write the ratio of cranberry juice to apple juice to orange juice in its simplest form.
Cranberry = 1 - 2/7 - 1/2 = 3/14
c:a:o = 3/14 : 4/14 : 7/14 = 3 : 4 : 7
