21/7 = 3 21/3 = 7 36/2 = 18 36/4 = 9 36/6 = 6 36/12 = 3 36/18 = 2 and, of course, both 21 and 36 can be divided by 1 and themselves

21/7 = 3 21/3 = 7 36/2 = 18 36/4 = 9 36/6 = 6 36/12 = 3 36/18 = 2 and, of course, both 21 and 36 can be divided by 1 and themselves
The ratio, as a fraction, is 7/12. The two steps are: -- Convert all units to inches (1 foot = 12 inches, so 3 feet = 36 inches) -- Reduce the ratio 21/36 (the numbers 21 and 36 have a GCF of 3) 21 divided by 3 = 7 36 divided by 3 is 12 21/36 = 7/12
