Question

2ч30мин-55мин столбиком решение

Answer 1

To solve the expression 2 hours 30 minutes minus 55 minutes, we can convert the hours and minutes into a common unit, which in this case will be minutes.

First, let's convert 2 hours and 30 minutes into minutes. Since there are 60 minutes in an hour, we can calculate:

2 hours = 2 * 60 minutes = 120 minutes 30 minutes = 30 minutes

So, 2 hours 30 minutes is equal to 120 minutes + 30 minutes = 150 minutes.

Next, we subtract 55 minutes from 150 minutes:

150 minutes - 55 minutes = 95 minutes.

Therefore, 2 hours 30 minutes minus 55 minutes is equal to 95 minutes.

Solution:

2 hours 30 minutes - 55 minutes = 95 minutes.
