1. Problem Description

The image presents a series of unit conversion problems:
a) Convert 25 gallons to pints.
b) Convert 20 weeks to days.
c) Calculate the distance in feet a leprechaun covers in 20 minutes at a speed of 2 miles per hour.
d) Convert 1,612,742 grams to kilograms.
e) Convert 3 grams, 7 decigrams, 5 centigrams, and 8 milligrams to milligrams.
f) Convert 8 cups to fluid ounces.

2. Solution Steps

a) Convert gallons to pints:
1 gallon = 8 pints
25 gallons=25×8 pints=200 pints25 \text{ gallons} = 25 \times 8 \text{ pints} = 200 \text{ pints}
b) Convert weeks to days:
1 week = 7 days
20 weeks=20×7 days=140 days20 \text{ weeks} = 20 \times 7 \text{ days} = 140 \text{ days}
c) Calculate the distance in feet:
Speed = 2 miles per hour
Time = 20 minutes = 2060\frac{20}{60} hours = 13\frac{1}{3} hour
Distance = Speed ×\times Time
Distance = 2 miles/hour×13 hour=23 miles2 \text{ miles/hour} \times \frac{1}{3} \text{ hour} = \frac{2}{3} \text{ miles}
1 mile = 5280 feet
Distance = 23 miles×5280 feet/mile=2×52803 feet=105603 feet=3520 feet\frac{2}{3} \text{ miles} \times 5280 \text{ feet/mile} = \frac{2 \times 5280}{3} \text{ feet} = \frac{10560}{3} \text{ feet} = 3520 \text{ feet}
d) Convert grams to kilograms:
1 kilogram = 1000 grams
1,612,742 grams=1,612,7421000 kilograms=1612.742 kilograms1,612,742 \text{ grams} = \frac{1,612,742}{1000} \text{ kilograms} = 1612.742 \text{ kilograms}
e) Convert grams, decigrams, centigrams, and milligrams to milligrams:
1 gram = 1000 milligrams
1 decigram = 100 milligrams
1 centigram = 10 milligrams
3 grams=3×1000 milligrams=3000 milligrams3 \text{ grams} = 3 \times 1000 \text{ milligrams} = 3000 \text{ milligrams}
7 decigrams=7×100 milligrams=700 milligrams7 \text{ decigrams} = 7 \times 100 \text{ milligrams} = 700 \text{ milligrams}
5 centigrams=5×10 milligrams=50 milligrams5 \text{ centigrams} = 5 \times 10 \text{ milligrams} = 50 \text{ milligrams}
8 milligrams=8 milligrams8 \text{ milligrams} = 8 \text{ milligrams}
Total milligrams = 3000+700+50+8=3758 milligrams3000 + 700 + 50 + 8 = 3758 \text{ milligrams}
f) Convert cups to fluid ounces:
1 cup = 8 fluid ounces
8 cups=8×8 fluid ounces=64 fluid ounces8 \text{ cups} = 8 \times 8 \text{ fluid ounces} = 64 \text{ fluid ounces}

3. Final Answer

a) 200 pt
b) 140 days
c) 3520 ft
d) 1612.742 kg
e) 3758 mg
f) 64 fl oz
