Answer 2

To convert the given measurements, we'll use the following conversion factors:

1 meter (m) = 100 centimeters (cm) 1 decimeter (dm) = 10 centimeters (cm) 1 kilogram (kg) = 1000 grams (g) 1 hour (h) = 60 minutes (min) 1 minute (min) = 60 seconds (s)

Let's calculate each of the given expressions step by step:

Conversion of 675 mm to cm:

Given: 675 mm To convert mm to cm, we divide by 10. 675 mm = 67.5 cm

Conversion of 84 dm3 cm to cm:

Given: 84 dm3 cm To convert dm3 cm to cm, we multiply by 10. 84 dm3 cm = 840 cm

Conversion of 8745 g to kg:

Given: 8745 g To convert g to kg, we divide by 1000. 8745 g = 8.745 kg

Conversion of 26 c + 28 kg to kg:

Given: 26 c + 28 kg To convert c to kg, we divide by 100. 26 c + 28 kg = 26/100 kg + 28 kg = 0.26 kg + 28 kg = 28.26 kg

Conversion of 650 min to h min:

Given: 650 min To convert min to h min, we divide by 60. 650 min = 10 h + 50 min

Conversion of 5 min 30 s to s:

Given: 5 min 30 s To convert min to s, we multiply by 60. 5 min 30 s = 5 * 60 s + 30 s = 300 s + 30 s = 330 s

Calculation of 6 t 26 kg - 4 c 58 kg:

Given: 6 t 26 kg - 4 c 58 kg To subtract the given values, we need to convert t to kg and c to kg. 6 t 26 kg - 4 c 58 kg = 6 * 1000 kg + 26 kg - 4/100 kg - 58 kg = 6000 kg + 26 kg - 0.04 kg - 58 kg = 5968.96 kg

Calculation of 7 cm 8 mm * 503:

Given: 7 cm 8 mm * 503 To multiply the given values, we need to convert cm to mm. 7 cm 8 mm * 503 = (7 * 10 mm + 8 mm) * 503 = 78 mm * 503 = 39234 mm

Calculation of 246 m 32 cm : 4:

Given: 246 m 32 cm : 4 To divide the given value by 4, we need to convert m to cm. 246 m 32 cm : 4 = (246 * 100 cm + 32 cm) : 4 = 24632 cm : 4 = 6158 cm

Calculation of 50 min 3 s - 46 min 25 s:

Given: 50 min 3 s - 46 min 25 s To subtract the given values, we need to convert min to s. 50 min 3 s - 46 min 25 s = (50 * 60 s + 3 s) - (46 * 60 s + 25 s) = 3000 s + 3 s - 2760 s - 25 s = 218 s

Calculation of 8 h 32 min + 17 h 48 min:

Given: 8 h 32 min + 17 h 48 min To add the given values, we need to convert h to min. 8 h 32 min + 17 h 48 min = (8 * 60 min + 32 min) + (17 * 60 min + 48 min) = 480 min + 32 min + 1020 min + 48 min = 1580 min

In conclusion: - 675 mm = 67.5 cm - 84 dm3 cm = 840 cm - 8745 g = 8.745 kg - 26 c + 28 kg = 28.26 kg - 650 min = 10 h + 50 min - 5 min 30 s = 330 s - 6 t 26 kg - 4 c 58 kg = 5968.96 kg - 7 cm 8 mm * 503 = 39234 mm - 246 m 32 cm : 4 = 6158 cm - 50 min 3 s - 46 min 25 s = 218 s - 8 h 32 min + 17 h 48 min = 1580 min
