Question

26 хв 19 с + 8 хв 47 с 4 доби 17 год + 3 доби 18 год 7 рокiв 5 мiс. - 3 роки 9 мic. 5 рокiв 8 мiс + 4 роки 9 мiс. 6 год 3 хв - 3 год 18 хв 35 хв 17с - 28 хв 37 с 8 год 46 хв + 4 год 27 с 8 дiб 3 год - 7 дiб 4 год

Answer 1

26 хв19с+8хв 47с=35хв6с,

4 доби 17год+3 доби 18 год=8 діб 11 год,

7 років 5міс.- 3 роки 9 міс.=3 роки 8 міс.,

5 років 8 міс.+ 4 роки 9 міс= 10 років 5 міс.

6 год.3 хв -3 год 18 хв=2 год 45 хв,

35хв 17 с-28 хв 37 с= 6 хв 40 с,

8 год 46 хв +4 год 27с =12 год 46 хв 27 с,

8 діб 3 год - 7 діб 4 год=23 год .

Answer 2

1)35хв 6 секунд;2)8 діб 11 годин;3)3 роки 8 місяців;4)10 років 5 місяців;5)2 години 45 хвилин;6)6 хвилин 40 секунд;7)12 годин 46 хвилин 27 секунд;8)23 години

Answer 3

To solve these arithmetic expressions, let's break them down step by step:

1. 26 minutes 19 seconds + 8 minutes 47 seconds: Add the minutes and seconds separately: 26 min + 8 min = 34 min 19 sec + 47 sec = 66 sec = 1 min and 6 sec Therefore, the result is 34 minutes 6 seconds.

2. 4 days 17 years + 3 days 18 years: Add the days and years separately: 4 days + 3 days = 7 days 17 years + 18 years = 35 years Therefore, the result is 7 days 35 years.

3. 7 years 5 months - 3 years 9 months: Subtract the years and months separately: 7 years - 3 years = 4 years 5 months - 9 months = -4 months (since the result is negative, we can convert it to years and months: -4 months = -1 year and 8 months) Therefore, the result is 4 years 8 months.

4. 5 years 8 months + 4 years 9 months: Add the years and months separately: 5 years + 4 years = 9 years 8 months + 9 months = 17 months (convert this to years and months: 17 months = 1 year and 5 months) Therefore, the result is 9 years 1 month.

5. 6 years 3 minutes - 3 years 18 minutes: Subtract the years and minutes separately: 6 years - 3 years = 3 years 3 minutes - 18 minutes = -15 minutes (since the result is negative, we can convert it to hours and minutes: -15 minutes = -1 hour and 15 minutes) Therefore, the result is 3 years 1 hour and 15 minutes.

6. 35 minutes 17 seconds - 28 minutes 37 seconds: Subtract the minutes and seconds separately: 35 min - 28 min = 7 min 17 sec - 37 sec = -20 sec (since the result is negative, we can convert it to minutes and seconds: -20 sec = -1 min and 20 sec) Therefore, the result is 7 minutes -1 minute 20 seconds.

7. 8 years 46 minutes + 4 years 27 seconds: Add the years and minutes separately: 8 years + 4 years = 12 years 46 minutes + 27 seconds = 46 minutes and 27 seconds Therefore, the result is 12 years 46 minutes and 27 seconds.

8. 8 days 3 years - 7 days 4 years: Subtract the days and years separately: 8 days - 7 days = 1 day 3 years - 4 years = -1 year Therefore, the result is 1 day -1 year.

Please note that for the results involving negative values, it's important to interpret them correctly. For instance, -1 year means one year before the reference point, and -1 minute means one minute before the reference point. Also, please double-check the accuracy of the calculations as errors can occur during manual computation.
