the length of one board is 2 feet 10 inches,and the length if anither board is 1 yard 1 foot 9 inches. what is the total length of the two boards put together?
First add the inches 10+9=19, then subtract 12 =7inches. Then add the feet and the foot taken from inches 2+1+1=4, subtract 3 =1foot. Then add the yard and the yard taken from feet 1+1=2yards. 2yards 1foot 7inches :)
