192*5=960мин

960:60 = 16 часов

7 мин19с=439с

439*8=3512с

3512с=58мин32с

4д18ч=114ч

114*3=342ч=14д6ч

13нед5д=96д

96*7=672д=96нед

Answer 2

Let's solve each of these calculations:

1. 8m20cm × 6: To multiply, we need to convert everything to the same units. Let's convert centimeters to meters first: 8m20cm = 8.20 meters Now, multiply: 8.20 meters × 6 = 49.20 meters

2. 15cm3mm × 4: To multiply, we need to convert everything to the same units. Let's convert millimeters to centimeters: 15cm3mm = 15.3 centimeters Now, multiply: 15.3 centimeters × 4 = 61.2 centimeters

3. 3h12min × 5: To multiply, we need to convert everything to the same units. Let's convert minutes to hours: 3 hours 12 minutes = 3.2 hours Now, multiply: 3.2 hours × 5 = 16 hours

4. 7min19s × 8: To multiply, we need to convert everything to the same units. Let's convert seconds to minutes: 7 minutes 19 seconds = 7.32 minutes Now, multiply: 7.32 minutes × 8 = 58.56 minutes

5. 4d.18h × 3: To multiply, we need to convert everything to the same units. Let's convert days to hours: 4 days = 4 × 24 hours = 96 hours Now, add the remaining 18 hours: 96 hours + 18 hours = 114 hours Now, multiply: 114 hours × 3 = 342 hours

6. 13ned.5d. × 7: To multiply, we need to convert everything to the same units. Let's convert weeks to days: 13 weeks = 13 × 7 days = 91 days Now, add the remaining 5 days: 91 days + 5 days = 96 days Now, multiply: 96 days × 7 = 672 days

So the results are:

1. 8m20cm × 6 = 49.20 meters
2. 15cm3mm × 4 = 61.2 centimeters
3. 3h12min × 5 = 16 hours
4. 7min19s × 8 = 58.56 minutes
5. 4d.18h × 3 = 342 hours
6. 13ned.5d. × 7 = 672 days
