1 feet is 12 inches.
We have 5 feet and 6 inches. First, let's convert the feet to inches. 5 times 12 is 60, so 5 feet is 60 inches.
Now add 60 inches to the 6 inches that we didn't mention. 60 plus 6 is 66. Thus, 5 feet and 6 inches is 66 inches.
Yes, if the rational number can be simplified like 2/10 (20) then yes it can be whole number.
It's eather a low number or a greater number
