Answer 1

3ч 45мин : 7 мин 30 сек=10800:450=24сек
16т 9ц : 50 кг=321кг8г
 5кв дм 25 кв см : 25 см=5см
48м 24см : 3дм 6см=134см
2км 325 м : 75м=31м
34км 290м : 90м=381м

Answer 2

Calculation: 3 hours 45 minutes + 7 minutes 30 seconds + 16 tons 9 centners + 50 kilograms 5 square decimeters 25 square centimeters + 25 centimeters 48 meters 24 centimeters + 3 decimeters 6 centimeters 2 kilometers 325 meters + 75 kilometers 34 meters 290 meters + 90 meters

To calculate this expression, let's break it down step by step:

1. Convert the time units to a common unit (seconds): - 3 hours 45 minutes = 3 * 60 * 60 seconds + 45 * 60 seconds = 13,500 seconds - 7 minutes 30 seconds = 7 * 60 seconds + 30 seconds = 450 seconds

The total time is 13,500 seconds + 450 seconds = 13,950 seconds.

2. Convert the weight units to a common unit (grams): - 16 tons 9 centners = 16 * 1000 * 100 * 100 grams + 9 * 100 * 100 grams = 16,090,000 grams + 900,000 grams = 16,990,000 grams - 50 kilograms = 50 * 1000 grams = 50,000 grams

The total weight is 16,990,000 grams + 50,000 grams = 17,040,000 grams.

3. Convert the area units to a common unit (square centimeters): - 5 square decimeters 25 square centimeters = 5 * 100 square centimeters + 25 square centimeters = 500 square centimeters + 25 square centimeters = 525 square centimeters

The total area is 525 square centimeters.

4. Convert the length units to a common unit (centimeters): - 25 centimeters 48 meters 24 centimeters = 25 centimeters + 48 * 100 centimeters + 24 centimeters = 25 centimeters + 4,800 centimeters + 24 centimeters = 4,849 centimeters - 3 decimeters 6 centimeters = 3 * 10 centimeters + 6 centimeters = 30 centimeters + 6 centimeters = 36 centimeters - 2 kilometers 325 meters = 2 * 1000 * 100 centimeters + 325 * 100 centimeters = 200,000 centimeters + 32,500 centimeters = 232,500 centimeters - 75 kilometers 34 meters 290 meters = 75 * 1000 * 100 centimeters + 34 * 100 centimeters + 290 centimeters = 7,500,000 centimeters + 3,400 centimeters + 290 centimeters = 7,503,690 centimeters - 90 meters = 90 * 100 centimeters = 9,000 centimeters

The total length is 4,849 centimeters + 36 centimeters + 232,500 centimeters + 7,503,690 centimeters + 9,000 centimeters = 7,749,075 centimeters.

5. Add up all the converted units: - Time: 13,950 seconds - Weight: 17,040,000 grams - Area: 525 square centimeters - Length: 7,749,075 centimeters

The final result is 13,950 seconds + 17,040,000 grams + 525 square centimeters + 7,749,075 centimeters.
