(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
