Answer 1

Ответ:1) 7920м. 2)450см. 3)4041мин.

Answer 2

To solve the given expressions, let's simplify each one:

1. 8 km 8 m - 88 m:

Since 1 km is equal to 1000 m, we can convert 8 km to meters:

8 km = 8,000 m

Now, let's subtract the values:

8,000 m + 8 m - 88 m = 7,920 m

So, 8 km 8 m - 88 m is equal to 7,920 meters.

2. 5 m 5 cm - 55 cm:

Since 1 m is equal to 100 cm, we can convert 5 m to centimeters:

5 m = 500 cm

Now, let's subtract the values:

500 cm + 5 cm - 55 cm = 450 cm

So, 5 m 5 cm - 55 cm is equal to 450 centimeters.

3. 7 h 29 min * 9:

To multiply hours and minutes, we need to convert them to a single unit, such as minutes.

7 h = 7 * 60 min = 420 min 29 min = 29 min

Now, let's calculate the multiplication:

(420 min + 29 min) * 9 = 4,041 min

So, 7 h 29 min * 9 is equal to 4,041 minutes.

Final answers:

• 8 km 8 m - 88 m = 7,920 meters
• 5 m 5 cm - 55 cm = 450 centimeters
• 7 h 29 min * 9 = 4,041 minutes
