Answer 1

9дм-6дм4см+24см=90см - 64см + 24 см = 26см + 24см = 50см = 5дм
1м8дм+42дм-2м7дм= 18дм + 42 дм - 27 дм = 60 дм - 27дм = 33дм = 3м3дм
3дм5см+4дм7см-69см= 35см + 47см - 69см = 82см-69см=13см=1дм3см
7м2дм-58дм+1м7дм=72дм-58дм+17дм=14дм+17дм=31дм=3м1дм

Answer 3

To solve this equation, you need to perform addition and subtraction with the given measurements. Keep in mind that 1 meter (м) equals 10 decimeters (дм) and 1 decimeter equals 10 centimeters (см). Let's break it down step by step:

1. Add and subtract the measurements in each equation:

   Equation 1: 9дм - 6дм 4см + 24см = 1м 8дм + 42дм - 2м 7дм = 3дм 5см + 4дм 7см - 69см = 7м 2дм - 58дм + 1м 7дм

2. Perform the addition and subtraction separately for each unit (meters, decimeters, centimeters):

   In meters (м):

   • 9дм - 6дм + 1м - 2м + 3дм - 69см + 7м + 1м = (7м + 1м) - (2м + 6дм + 69см) + (3дм - 9дм)

   Now, let's calculate each part separately:

   • 7м + 1м = 8м
   • 2м + 6дм + 69см = 2м + 60см + 69см = 2м + 129см = 2м 12дм 9см
   • 3дм - 9дм = -6дм

3. Now, put these results together:

   8м - (2м 12дм 9см) - 6дм = 8м - 2м 12дм 9см - 6дм

4. Perform subtraction for decimeters:

   8м - 2м - 6дм - 12дм = 6м - 18дм

So, the simplified equation is:

6 meters - 18 decimeters
