Example 10 Do the ratios 15 cm to 2 m and 10 sec to 3 minutes form a proportion?2m = 2 ร 100 cm = 200 cm 3 min = 3 ร 60 sec = 180 sec 15 cm : 2 m = (15 ๐๐)/(2 ๐) = (15 ๐๐)/(200 ๐๐) = 15/200 = 3/40 = 3 : 40 10 sec : 3 min = (10 ๐๐)/(3 ๐๐๐) = (10 ๐ ๐)/(180 ๐ ๐๐) = 10/180 = 1/18 = 1 : 18 โด 15 cm : 2 m โ 10 sec : 3 min Thus, Given ratios are not in proportion
