Questions:

1. How many grams are in 0.68 pounds?
2. The sleeve of a shirt is 20.0 inches long. How many micrometers is the shirt sleeve?
3. How many kilometers per decade are you traveling when you go 5 miles per hour?
4. How many deciliters are in 2.0 gallons?

0.68 pounds to grams is 308.72 grams, 20 inches to micrometers is 508,000 micrometers, 5 miles per hour to kilometers per decade is 0.917 km/decade, and 2 gallons to deciliters is 75.7 deciliters.

Explanation:

1. To convert 0.68 pounds to grams, use the conversion factor: 1 lb = 454 g. So, 0.68 pounds = 0.68 * 454 = 308.72 grams.

2. To convert 20 inches to micrometers, use the conversion factor: 1 in = 2.54 cm = 25,400 μm. So, 20 inches = 20 * 25,400 = 508,000 micrometers.

3. To convert 5 miles per hour to kilometers per decade, first convert miles to kilometers (1 mi = 1.609 km) then convert per hour to per decade (1 hr = 10 years and there are 87660 hours in a decade). So, 5 miles/hour = 5 * 1.609 km/hr = 8.045 km/hr = (8.045 km/hr) * (1 decade/87660 hours) = 0.917 km/decade.

4. To convert 2 gallon to deciliters, use the conversion factor: 1 US gal = 37.85 dl. So, 2 US gallons = 2 * 37.85 = 75.7 deciliters.
