Answer

(a) 1 pound = 16 ounces (b) 10 pints = 20 cups; 10 quarts = 20 pints (c) 120 seconds = 2 minutes; 120 minutes = 2 hours (d) 2 feet = 24 inches (e) 2000 pounds = 1 ton (f) 35 days = 5 weeks

Work Step by Step

(a) 1 pound = 16 ounces (b) We know that 10:20 reduces to 1:2. There are a few possibilities: 10 pints = 20 cups 10 quarts = 20 pints (c) We know that 120:2 reduces to 60:1. There are a few possibilities: 120 seconds = 2 minutes 120 minutes = 2 hours (d) We know that 2:24 reduces to 1:12. 2 feet = 24 inches (e) We know that 6000:3 reduces to 2000:1 2000 pounds = 1 ton (f) We know that 35:5 reduces to 7:1 35 days = 5 weeks
