In working with denominate numbers, we find a change from abstract numbers which do not represent measures. Instead of there being 10 inches in a foot, there are 12. Instead of 10 feet making a yard, 3 feet make a yard. That is, the number of units of a lower denomination that is required to make a unit of a higher denomination changes with the denomination that we are using

of corn.

Exercise 11. Addition of Denominate Numbers

1. A rectangular room is 13 feet 6 inches long and 10 feet 8 inches wide. Find the distance around the room.

Feet Inches
13 6

There are two sides, each 13 feet 6 inches, and two 13

ends, each 10 feet 8 incues. Adding the number of 6

inches=28. 28 inches=2 feet 4 inches. Place the 4 10 8

under the inches column and add the 2 feet to the 10 8

numbers in the feet column, making 48 feet. The 48 4

distance around the room is 48 feet 4 inches. Add the following:

2. 4 feet 3 inches; 5 feet 2 inches; 3 feet 9 inches and 7 feet 8 inches.

3. 2 pounds 5 ounces; 3 pounds 3 ounces; 2 pounds 11 ounces and 4 pounds 1 ounce.

4. 3 bushels 2 pecks; 2 bushels 3 pecks; 3 bushels 1 peck and 5 bushels 1 peck.

5. 1 square foot 42 square inches; 2 square feet 88 square inches and 4 square feet 112 square inches.

6. 3 quarts 1 pint; 2 quarts 1 pint; 6 quarts 1 pint and 5 quarts 1 pint.

Exercise 12. Subtraction of Denominate Numbers

1. From a bolt of cloth containing 18 yards 8 inches a clerk cut a piece 7 yards 18 inches. How much was left? Yards Inches

We can not subtract 18 inches from 8 inches, so we 18 8 must change one of the 18 yards to inches, making 36 7 18

inches. 36 inches +8 inches=44 inches. 44 inches

18 inches26 inches. 17 yards—7 yards=10 yards. 10 26

10 yards 26 inches may be expressed as 10 yards 2 feet

2 inches. Subtract the following: 2. 10 bushels 3 pecks – 8 bushels 2 pecks. 3. 5 gallons 2 quarts-4 gallons 3 quarts. 4. 11 feet 6 inches-5 feet 4 inches. 5. 39 tons 500 pounds – 15 tons 1750 pounds. 6. 4 rods 12 feet-2 rods 15 feet. 7. 8 pounds 8 ounces-6 pounds 4 ounces.

8. 10 square feet 124 square inches — 2 square feet 24 square inches.

9. 16 acres 80 square rods – 10 acres 120 square rods. 10. 15 bushels 5 quarts – 10 bushels 17 quarts.

3 yards +2=1 yard with a remainder of 1 yard. 1 yard 22 inches 1 yard=36 inches. 36 inches +8 inches=44

inches. 44 inches =2=22 inches. Each piece 23 yards 8 inches

was 1 yard 22 inches or 1 yard 1 foot 10 inches long.

Divide:

2. 17 yards 2 feet by 2. 3. 4 pounds ounces by 3. 4. 25 yards 2 feet 9 inches by 3. 5. 5 hours 30 minutes by 2. 6. 1 pound 8 ounces by 4. 7. 12 rods 4 yards by 5. 8. 20 pounds 6 ounces by 6. 9. 2 yards 2 feet by 4. 10. 5 cubic feet 172 cubic inches by 4. 11. 4 yards 2 feet 8 inches by 2. 12. 5 hours 20 minutes by 8. 13. 10 feet 3 inches by 3.
