Answer 1

15 дм 4 см + 53 дм 5 см равно 68 дм 9 см

Answer 2

Let's perform the calculations step by step:

1. Addition of lengths: 15 dm 4 cm + 53 dm 5 cm = (15 + 53) dm + (4 + 5) cm = 68 dm + 9 cm

2. Subtraction of lengths: 76 cm 3 mm - 41 cm 2 mm = (76 - 41) cm + (3 - 2) mm = 35 cm + 1 mm

3. Addition of lengths: 37 р 20 к + 45 р 69 к = (37 + 45) р + (20 + 69) к = 82 р + 89 к

4. Subtraction of masses: 85 ц 33 кг - 16 ц 13 кг = (85 - 16) ц + (33 - 13) кг = 69 ц + 20 кг

5. Addition of masses: 23 кг 560 г + 11 кг 300 г = (23 + 11) кг + (560 + 300) г = 34 кг + 860 г

6. Subtraction of lengths: 15 км 248 м - 13 км 101 м = (15 - 13) км + (248 - 101) м = 2 км + 147 м

7. Addition of masses: 42 т 250 кг + 59 т 790 кг + 59 т 730 кг = (42 + 59 + 59) т + (250 + 790 + 730) кг = 160 т + 1770 кг

8. Subtraction of lengths: 67 м 384 мм - 19 м 200 мм = (67 - 19) м + (384 - 200) мм = 48 м + 184 мм

Please note that some units might be unfamiliar, as they are not commonly used in the International System of Units (SI). The answers are given in the given units. If you require the results in SI units, let me know and I can convert them accordingly.
