Question

2Ч 17МИН+43МИН= 1М23СМ-53СМ= 2Ц48КГ-57КГ

Answer 1

2 ч 17 мин + 43 мин = 3 ч
1 м 23 см - 53 = 70 см
2 ц 48 кг - 57 кг = 2 ц 9 кг

Answer 2

Let's solve the equations step by step:

1. Adding time: 2Ч (2 hours) 17МИН (17 minutes) + 43МИН (43 minutes)

To add minutes, we need to make sure that both times are in the same units. So, we add the hours and the minutes separately:

2 hours + 43 minutes = 2 hours + 43/60 hours (since there are 60 minutes in an hour) = 2 hours + 0.7167 hours = 2.7167 hours

Now, let's add the 17 minutes:

2.7167 hours + 17/60 hours = 2.7167 hours + 0.2833 hours ≈ 2.9999 hours

So, 2Ч 17МИН + 43МИН ≈ 2Ч 59МИН.

2. Subtracting time: 1М (1 minute) 23С (23 seconds) + 53С (53 seconds) = 1М (1 minute) 23С (23 seconds) - 53С (53 seconds)

To subtract seconds, we need to make sure that both times are in the same units. So, we add the minutes and the seconds separately:

1 minute + 53 seconds = 1 minute + 53/60 minutes (since there are 60 seconds in a minute) = 1 minute + 0.8833 minutes ≈ 1.8833 minutes

Now, let's subtract the 23 seconds:

1.8833 minutes - 23/60 minutes = 1.8833 minutes - 0.3833 minutes ≈ 1.5 minutes

So, 1М 23С - 53С ≈ 1М 30С.

3. Subtracting weight: 2Ц (2 hundredweight) 48КГ (48 kilograms) - 57КГ (57 kilograms)

To subtract kilograms, we simply subtract the two values:

48 kilograms - 57 kilograms = -9 kilograms

Note: Since the result is negative, it implies that the second weight is larger than the first one by 9 kilograms.

So, 2Ц 48КГ - 57КГ = 2Ц 39КГ.

Please note that some symbols like "Ч," "МИН," "СМ," "Ц," and "КГ" are not standard mathematical notation. It's essential to use standard symbols like "h" for hours, "m" for minutes, "s" for seconds, and "kg" for kilograms to avoid confusion.
