Question

8ч-43мин= 15м-18дм= ​

Answer 1

Ответ:

8ч - 43мин = 7ч 17 мин

15м - 18дм = 13м 2дм

Пошаговое объяснение:

8часов = 480 минут

480мин - 43мин = 437 мин = 7ч 17мин

15м = 150дм

150дм - 18дм = 132дм = 13м 2дм

Элементарно!

Answer 2

Посмотри, надеюсь понятно

Answer 3

To solve these subtractions, let's first convert all units to the same unit (minutes) to make the calculations easier.

1. 8 hours and 43 minutes: 8 hours = 8 * 60 minutes = 480 minutes So, 8 hours and 43 minutes = 480 minutes + 43 minutes = 523 minutes

2. 15 meters and 18 decimeters: 1 meter = 10 decimeters 15 meters = 15 * 10 decimeters = 150 decimeters So, 15 meters and 18 decimeters = 150 decimeters + 18 decimeters = 168 decimeters

Now, let's subtract them: 523 minutes - 168 decimeters

Since these are different units, we cannot directly subtract them. We need to convert one of the units to the other unit. Let's convert minutes to decimeters.

1 minute is equivalent to 0.1 decimeters (assuming some arbitrary conversion rate for illustration purposes).

523 minutes = 523 * 0.1 decimeters = 52.3 decimeters

Now we can subtract:

52.3 decimeters - 168 decimeters = -115.7 decimeters

So, the result of the subtraction is approximately -115.7 decimeters. The negative sign indicates that the result is negative.
