Answer 1

10 KM 875 M+ 925м=9 КМ 950м

12 т 015 кг --98кг=11т 917кг

15 м2 25дм2 --50дм2=14м2 975дм2

20 дм2 30 см2 +80см2 =21дм2 10см2

17 м 30 см •6 =103м 80см

25 ц 80 кг :3=8ц 60кг

38 см 5 мм + 8 мм=393см

5 ар 60 м2 + 40 м2 =6ар

Answer 3

To perform the calculations, let's solve each expression step by step:

1. 10 km 875 m + 925 m:

   • Convert 10 km to meters: 10 km = 10,000 m
   • Add the meters together: 10,000 m + 875 m + 925 m = 11,800 m

2. 12 t 015 kg - 98 kg:

   • Subtract the kilograms: 12,015 kg - 98 kg = 11,917 kg

3. 15 m² 25 dm² - 50 dm²:

   • Convert the square meters to square decimeters: 15 m² = 15,000 dm²
   • Subtract the square decimeters: 15,000 dm² + 25 dm² - 50 dm² = 14,975 dm²

4. 20 dm² 30 cm² + 80 cm²:

   • Convert the square centimeters to square decimeters: 30 cm² = 3 dm²
   • Add the square decimeters together: 20 dm² + 3 dm² + 80 cm² = 23 dm² + 80 cm²

5. 17 m 30 cm * 6:

   • Convert 17 m to centimeters: 17 m = 1,700 cm
   • Multiply by 6: 1,700 cm * 6 = 10,200 cm

6. 25 c 80 kg ÷ 3:

   • Convert 25 c to kilograms: 25 c = 2,500 kg
   • Divide by 3: 2,500 kg ÷ 3 = 833.33 kg (rounded to two decimal places)

7. 38 cm + 5 mm + 8 mm:

   • Convert 5 mm and 8 mm to centimeters: 5 mm = 0.5 cm, 8 mm = 0.8 cm
   • Add the centimeters together: 38 cm + 0.5 cm + 0.8 cm = 39.3 cm

8. 60 m² + 40 m²:

   • Add the square meters together: 60 m² + 40 m² = 100 m²

Therefore, the results are as follows:

• 11,800 m
• 11,917 kg
• 14,975 dm²
• 23 dm² + 80 cm²
• 10,200 cm
• 833.33 kg
• 39.3 cm
• 100 m²
