Twelve over twelve as a mixed number can't appear as a mixed number like one and three fourths, so twelve over twelve equals a whole, or AKA, 1. There's your answer.

One Yard equals three feet. Thus, four yards equals twelve feet. One foot has twelve inches. If you take the four yards (twelve feet), and add them to three feet, you get fifteen feet. Take the fifteen feet, each one containing twelve inches, and multiply them by twelve. Fifteen times twelve equals 180. Therefore, there are 180 inches in four yards, three feet. 4 (yards) x 3 = 12 (feet) 12+3= 15 (feet) 15 x 12 = 180 (inches)
