Answer 3

To solve the given equations, let's perform the calculations step by step:

406 cm + 3 dm 9 cm: First, let's convert 3 dm to cm. Since 1 dm is equal to 10 cm, we have: 3 dm = 3 x 10 cm = 30 cm

Now, we can add the lengths: 406 cm + 30 cm + 9 cm = 406 cm + 39 cm = 445 cm

6 cm 4 dm 7 cm - 5 dm 8 cm: First, let's convert 5 dm to cm: 5 dm = 5 x 10 cm = 50 cm

Now, we can subtract the lengths: 6 cm 4 dm 7 cm - 50 cm 8 cm = 6 cm 4 dm (7 cm - 50 cm) - 8 cm

Since 7 cm is smaller than 50 cm, we need to borrow 1 dm (10 cm) from the 4 dm: 6 cm 3 dm 17 cm - 8 cm = 6 cm 3 dm (17 cm - 8 cm) = 6 cm 3 dm 9 cm

Therefore, the result is 6 cm 3 dm 9 cm.

647 cm - 58 cm: 647 cm - 58 cm = 589 cm

So, the final result is 589 cm.
