Question

9м-52дм+4м 6дм= 2дм 5см+5дм 4см-38см= 7дм 2см+1дм 8см-23см= 6м-1м 7дм+3м 2дм=

Answer 1

9 м - 52 дм + 4 м 6 дм =90 дм - 52 дм + 46 дм= 38 дм+ 46 дм =84 дм = 8м4дм 
2 дм 5 см + 5 дм 4 см - 38 см =25 см + 54 см - 38 см= 41 см = 4 дм 1 см
7 дм 2 см + 1 дм 8 см- 23 см  = 72 см + 18 см - 23 см = 67 см = 6 дм 7 см 
6 м - 1 м 7 дм +3 м 2 дм = 60 дм - 17 дм + 32 дм = 75 дм =7 м 5 дм

Answer 2

To solve these arithmetic operations, let's break them down step by step:

1. 9m - 52dm + 4m 6dm: First, convert the measurements to a consistent unit. Let's convert everything to decimeters (dm): 9m = 90dm 4m = 40dm Now, we can perform the addition and subtraction: 90dm - 52dm + 40dm + 6dm = 84dm

   Therefore, 9m - 52dm + 4m 6dm equals 84 decimeters (dm).

2. 2dm 5cm + 5dm 4cm - 38cm: Convert everything to centimeters (cm): 2dm 5cm = 25cm 5dm 4cm = 54cm Now, we can perform the addition and subtraction: 25cm + 54cm - 38cm = 41cm

   Therefore, 2dm 5cm + 5dm 4cm - 38cm equals 41 centimeters (cm).

3. 7dm 2cm + 1dm 8cm - 23cm: Convert everything to centimeters (cm): 7dm 2cm = 72cm 1dm 8cm = 18cm Now, we can perform the addition and subtraction: 72cm + 18cm - 23cm = 67cm

   Therefore, 7dm 2cm + 1dm 8cm - 23cm equals 67 centimeters (cm).

4. 6m - 1m 7dm + 3m 2dm: Convert everything to decimeters (dm): 6m = 60dm 1m 7dm = 17dm 3m 2dm = 32dm Now, we can perform the addition and subtraction: 60dm - 17dm + 32dm = 75dm

   Therefore, 6m - 1m 7dm + 3m 2dm equals 75 decimeters (dm).

Please note that these calculations assume no carrying or borrowing between units during the addition and subtraction process.
