Answer 2

2м34см+5м11см=745см=7м4дм5см

2м3дм4см+1м4дм4см=378см=3м7дм8см

45дм+3м3см=753см=

7м5дм3см

3м5дм9см-1м4дм4см=215см=2м1дм5см

67дм5см-3м2см=373см=3м7дм3см

6м9дм7см-2м45см=452см=4м5дм2см

Answer 3

To solve these addition and subtraction problems with different units of measurement, we need to convert them all into the same unit. Let's convert everything to centimeters (cm) to simplify the calculations:

• 2м34см = (2 x 100) + 34 = 234 cm
• 5м11см = (5 x 100) + 11 = 511 cm
• 2м3дм4см = (2 x 1000) + (3 x 100) + 4 = 2304 cm
• 1м4дм4см = (1 x 100) + (4 x 10) + 4 = 144 cm
• 45дм = 45 x 10 = 450 cm
• 3м3см = (3 x 100) + 3 = 303 cm
• 3м5дм9см = (3 x 100) + (5 x 10) + 9 = 359 cm
• 1м4дм4см = (1 x 100) + (4 x 10) + 4 = 144 cm
• 67дм5см = 67 x 10 + 5 = 675 cm
• 3м2см = (3 x 100) + 2 = 302 cm
• 6м9дм7см = (6 x 100) + (9 x 10) + 7 = 697 cm
• 2м45см = (2 x 100) + 45 = 245 cm

Now we can solve each problem:

• 234 + 511 = 745 cm
• 2304 + 144 = 2448 cm
• 450 + 303 = 753 cm
• 359 - 144 = 215 cm
• 675 - 302 = 373 cm
• 697 - 245 = 452 cm

Therefore, the solutions to each problem are:

• 2м34см + 5м11см = 745 сm
• 2м3дм4см + 1м4дм4см = 2448 сm
• 45дм + 3м3см = 753 сm
• 3м5дм9см - 1м4дм4см = 215 сm
• 67дм5см - 3м2см = 373 сm
• 6м9дм7см - 2м45см = 452 сm
