8 15 3 15
EXPLANATION: (1) Place as in addition of denominate quantities. 10
ounces cannot be taken from 9 ounces, so we must take 1 pound from the
13 pounds and add it to the nine ounces. 16 ounces + 9 ounces = 25
ounces. 25 - 10 = 15. Write the 15 below.
(2) Now there are only 12 pounds left to take the 9 from. 12 - 9 = 3.
Write the 3 below.
(3) 12 is larger than 7. 1 ton + 7 cwt. = 27 cwt. 27 - 12 = 15. Write
the 15 below.
(4) 14 - 6 = 8. Write the 8 below.
(5) Result = 8 tons 15 cwt. 3 pounds 15 ounces.
