Converting (Customary) 16 Oz =1 lb 2000 lbs = 1 T 32000 oz = 1 T Converting (Metric) g = 1 kg 1000

Question: How many pounds are in 5 tons? 16 oz = 1 lb 2000 lbs = 1 ton 32000 oz = 1 ton 1000 grams = 1 kg Write the question: Choose the ratio: 1 ton 2000 lbs 5 tons lbs Set up the proportion: Solve 5 tons lbs 1 ton 2000 lbs 5 x 2000 ÷ 1 = 10,000 = So, 5 tons = 10,000 lbs

Question: How many tons are in 7000 lbs? 16 oz = 1 lb 2000 lbs = 1 ton 32000 oz = 1 ton 1000 grams = 1 kg Write the question: Choose the ratio: 7000 lbs tons 2000 lbs 1 ton Set up the proportion: Solve 7000 lbs tons 2000 lbs 1 ton 7000 x 1 ÷ 2000 = 10,000 = So, 7000 lbs = 3.5 tons

Question: How many ounces are in 2.5 lbs? 16 oz = 1 lb 2000 lbs = 1 ton 32000 oz = 1 ton 1000 grams = 1 kg Write the question: Choose the ratio: 2.5 lbs oz 1 lb 16 oz Set up the proportion: Solve 2.5 lbs oz 1 lbs 16 oz 16 x 2.5 ÷ 1 = 40 = So, 2.5 lbs = 40 oz

Question: How many pounds are in 48 oz? 16 oz = 1 lb 2000 lbs = 1 ton 32000 oz = 1 ton 1000 grams = 1 kg Write the question: Choose the ratio: 48 oz lbs 16 oz 1 lb Set up the proportion: Solve 48 oz lbs 16 oz 1 lb 48 x 1 ÷ 16 = 3 = So, 48 oz = 3 lbs

Question: How many kg are in 1500 grams? 16 oz = 1 lb 2000 lbs = 1 ton 32000 oz = 1 ton 1000 grams = 1 kg Write the question: Choose the ratio: 1500 gram kg 1000 gram 1 kg Set up the proportion: Solve 1500 g kg 1000 g 1 kg 1500 x 1 ÷ 1000 = 1.5 = So, 1500 grams = 1.5 kg

Question: How many oz are in 2.5 tons? 16 oz = 1 lb 2000 lbs = 1 ton 32000 oz = 1 ton 1000 grams = 1 kg Write the question: Choose the ratio: 2.5 ton oz 1 ton 32000 oz Set up the proportion: Solve 2.5 ton oz 1 ton 32000 oz 2.5 x 32000 ÷ 1 = 80,000 = So, 2.5 tons = 80,000 oz

Question: How many tons are in 60,000 oz? 16 oz = 1 lb 2000 lbs = 1 ton 32000 oz = 1 ton 1000 grams = 1 kg Write the question: Choose the ratio: 60,000 oz ton 32000 oz 1 ton Set up the proportion: Solve 60000 oz ton 32000 oz 1 ton 60000 x 1 ÷ 32000 = 1.9 ton = So, 60,000 oz = 1.9 tons
