Converting Units using Ratio Reasoning

To convert feet to inches, multiply by 12. Thus, 2 feet = 2 x 12 = 24 inches. For yards, 1 yard = 36 inches, so 2 yards = 2 x 36 = 72 inches and 4 yards = 4 x 36 = 144 inches. 2 yards = 6 feet.

To convert feet to inches, multiply the number of feet by 12. Therefore, 7 feet x 12 inches/foot = 84 inches. Thus, the correct answer is 84 inches.

To convert 5 feet 10 inches to inches, first convert feet to inches: 5 ft x 12 in/ft = 60 in. Then add the 10 inches: 60 in + 10 in = 70 in. Therefore, the correct answer is 70 inches.

To convert feet to yards, divide the number of feet by 3. Thus, 99 feet ÷ 3 = 33 yards. Therefore, the correct answer is 33 yards.

To convert yards to feet, multiply by 3 (since 1 yard = 3 feet). Therefore, 6 yards = 6 x 3 = 18 feet. The correct answer is 18 feet.

1/2 ft is equivalent to 6 inches, since 1 ft equals 12 inches. Therefore, 1/2 ft or 0.5 ft equals 6 inches, making the correct answer 6.

To convert miles to feet, use the fact that 1 mile = 5280 feet. Therefore, 1/4 of a mile = 5280 / 4 = 1320 feet. Thus, the correct answer is 1320.

To convert pounds to ounces, multiply by 16 (since 1 pound = 16 ounces). Therefore, 12 pounds = 12 x 16 = 192 ounces. The correct answer is 192.

To convert quarts to gallons, divide the number of quarts by 4. Thus, 15 quarts ÷ 4 = 3.75 gallons, which is equivalent to 3 3/4 gallons. Therefore, the correct answer is 3 3/4.

To convert feet to miles, divide the number of feet by 5,280 (the number of feet in a mile). Thus, 21,120 feet ÷ 5,280 feet/mile = 4 miles. Therefore, the correct answer is 4.
