Mixed numbers can be added, subtracted, multiplied, or divided by changing them to improper fractions and proceeding as when performing the operations with other fractions.
A piece of tubing 6 3/16 inches long is cut from a piece 24 1/2 inches long. Allowing 1/16 inch for the cut, what is the length of the remaining piece?
FIRST: Reduce the fractional parts to like fractions and complete the subtraction process.
NEXT: Subtract the integer parts.
24 - 6 = 18
THEN: Combine the results obtained in each step.
