Hubby · Answer 1

9 and 1/12 inches. So 5 times 4 1/3 would be 65/3 which is the same as 260/12. 30 3/4 would be 369/12-260/12 which is 109/12, it then becomes 9 and 1/12 inches

Jordon Mitchell · Answer 2

9 and 1/12 inches of pipe remain because

30 and 3/4 = 30 and 9/12

4 and 1/3 = 4 and 4/12

4 and 4/12 x 5 = 20 and 20/12

which can be simplified to 21 and 8/12

30 and 9/12 - 21 and 8/12 = 9 and 1/12.
