Answer 1

4мин 45с·4=285с·4=1140с=19мин
12т 45ц·4=1245ц·4=4980ц=49т 80ц
12т 45ц·7=1245ц·7=8715ц=87т 15ц
4руб 15коп·4=415коп·4=1660коп=16руб 60коп
4руб 165коп·7=565коп·7=3955коп=39руб 55 ( а если в примере опечатка, тогда: 4руб 15коп·7=415коп·7=2905коп=29руб 5коп)

Answer 2

To calculate the result of the given expressions, let's take them one by one:

1. 4 minutes 45 seconds * 4 Time calculation: 4 minutes 45 seconds = 4 * 60 seconds + 45 seconds = 240 seconds + 45 seconds = 285 seconds Result: 285 seconds * 4 = 1140 seconds

2. 12 rubles 45 kopeks * 4 Monetary calculation: 12 rubles 45 kopeks = 12.45 rubles Result: 12.45 rubles * 4 = 49.80 rubles

3. 12 rubles 45 kopeks * 7 Monetary calculation: 12 rubles 45 kopeks = 12.45 rubles Result: 12.45 rubles * 7 = 87.15 rubles

4. 4 rubles 15 kopeks * 4 Monetary calculation: 4 rubles 15 kopeks = 4.15 rubles Result: 4.15 rubles * 4 = 16.60 rubles

5. 4 rubles 165 kopeks * 7 Monetary calculation: 4 rubles 165 kopeks = 4.165 rubles Result: 4.165 rubles * 7 = 29.155 rubles

Now, adding up the results:

1140 seconds + 49.80 rubles + 87.15 rubles + 16.60 rubles + 29.155 rubles

Since the units are different (seconds and rubles), they cannot be directly added together. If you want a single result, you need to convert the time duration to a monetary value (e.g., by considering an hourly wage) or convert the monetary value to a time duration (e.g., by considering an hourly rate). Please provide additional information if you want a specific conversion method.
