Answer 3

Ответь подробно.

1. Сравни, поставь знаки <, >, =:

5 км 4 м ... 5 км 40 дм: To compare 5 km 4 m and 5 km 40 dm, let's convert both to the same unit, such as meters. 5 km = 5000 m (1 km = 1000 m) 5 km 4 m = 5004 m 5 km 40 dm = 5040 dm = 504 m (1 m = 10 dm)

So, 5004 m > 504 m

245 ч ... 4 сут 5 ч: To compare 245 hours and 4 days 5 hours, let's convert both to hours. 4 days = 4 * 24 = 96 hours 4 days 5 hours = 96 + 5 = 101 hours

So, 245 hours > 101 hours

200 кг ... 62000 кг: 200 kg < 62000 kg

2. Реши уравнение:

84 ÷ x = 6 • 7 To solve for x, we can start by multiplying 6 and 7, then divide 84 by the result.

6 • 7 = 42 84 ÷ x = 42

To solve for x, we can multiply both sides by x to isolate x: 84 = 42x

Then divide both sides by 42 to solve for x: x = 84 ÷ 42 x = 2

So, the solution to the equation 84 ÷ x = 6 • 7 is x = 2.
