Answer 2

To solve these arithmetic calculations, let's go through each one step by step:

1. 19 km 78 m + 38 km 976 m To add these two distances, we need to convert them to the same unit. Let's convert them to meters: 19 km 78 m = 19,078 m 38 km 976 m = 38,976 m Now, we can add them: 19,078 m + 38,976 m = 58,054 m So, 19 km 78 m + 38 km 976 m = 58,054 m

2. 2 m 96 dm 93 mm + 77 dm 9 mm Let's convert them to the same unit, millimeters: 2 m 96 dm 93 mm = 2,9693 mm 77 dm 9 mm = 770,9 mm Now, we can add them: 2,9693 mm + 770,9 mm = 773,8693 mm So, 2 m 96 dm 93 mm + 77 dm 9 mm = 773,8693 mm

3. 56 dm 28 mm + 24 dm 77 mm Let's convert them to the same unit, millimeters: 56 dm 28 mm = 5,628 mm 24 dm 77 mm = 2,477 mm Now, we can add them: 5,628 mm + 2,477 mm = 8,105 mm So, 56 dm 28 mm + 24 dm 77 mm = 8,105 mm

4. 12 m 57 cm - 8 m 96 cm Let's convert them to the same unit, centimeters: 12 m 57 cm = 1,257 cm 8 m 96 cm = 896 cm Now, we can subtract them: 1,257 cm - 896 cm = 361 cm So, 12 m 57 cm - 8 m 96 cm = 361 cm

5. 66 dm 5 mm - 28 dm 18 mm Let's convert them to the same unit, millimeters: 66 dm 5 mm = 6,605 mm 28 dm 18 mm = 2,818 mm Now, we can subtract them: 6,605 mm - 2,818 mm = 3,787 mm So, 66 dm 5 mm - 28 dm 18 mm = 3,787 mm

6. 12 km 24 dm - 9 km 29 dm Let's convert them to the same unit, decimeters: 12 km 24 dm = 120,240 dm 9 km 29 dm = 90,290 dm Now, we can subtract them: 120,240 dm - 90,290 dm = 29,950 dm So, 12 km 24 dm - 9 km 29 dm = 29,950 dm

7. 8 dm 28 mm * 4 To multiply, we can simply multiply the whole number and the decimal separately: 8 * 4 = 32 (whole number) 28 mm * 4 = 112 mm So, 8 dm 28 mm * 4 = 32 dm 112 mm

8. 24 dm 7 cm * 7 To multiply, we can simply multiply the whole number and the decimal separately: 24 * 7 = 168 (whole number) 7 cm * 7 = 49 cm So, 24 dm 7 cm * 7 = 168 dm 49 cm

9. 15 km 240 m / 4 To divide, we can divide the whole number and the decimal separately: 15 km / 4 = 3.75 km 240 m / 4 = 60 m So, 15 km 240 m / 4 = 3.75 km 60 m

10. 17 cm 8 mm * 9 To multiply, we can simply multiply the whole number and the decimal separately: 17 * 9 = 153 (whole number) 8 mm * 9 = 72 mm So, 17 cm 8 mm * 9 = 153 cm 72 mm

11. 21 km 490 m / 7 To divide, we can divide the whole number and the decimal separately: 21 km / 7 = 3 km 490 m / 7 = 70 m So, 21 km 490 m / 7 = 3 km 70 m

12. 33 dm 27 mm / 3 To divide, we can divide the whole number and the decimal separately: 33 / 3 = 11 (whole number) 27 mm / 3 = 9 mm So, 33 dm 27 mm / 3 = 11 dm 9 mm

13. 15 m 45 cm / 5 To divide, we can divide the whole number and the decimal separately: 15 / 5 = 3 (whole number) 45 cm / 5 = 9 cm So, 15 m 45 cm / 5 = 3 m 9 cm

14. 8 km 327 m * 6 + 6 km 42 m * 15 - 2 km 7 m * 8 To solve this expression, let's calculate each part separately and then perform the operations: 8 km 327 m * 6 = 49 km 962 m 6 km 42 m * 15 = 90 km 630 m 2 km 7 m * 8 = 16 km 56 m Now, let's perform the operations: 49 km 962 m + 90 km 630 m - 16 km 56 m = 123 km 536 m

So, the answers to the given arithmetic calculations are: 1. 58,054 m 2. 773,8693 mm 3. 8,105 mm 4. 361 cm 5. 3,787 mm 6. 29,950 dm 7. 32 dm 112 mm 8. 168 dm 49 cm 9. 3.75 km 60 m 10. 153 cm 72 mm 11. 3 km 70 m 12. 11 dm 9 mm 13. 3 m 9 cm 14. 123 km 536 m
