27см+28см+43см-35см=63см=6дм3см

Answer 2

To add the given measurements, we need to ensure that all the units are the same. Let's convert all the measurements to centimeters and then perform the addition.

1 centimeter (см) = 10 millimeters (мм) 1 decimeter (дм) = 10 centimeters (см)

Given: 27 см + 2 дм 8 см + 4 дм 3 см - 3 дм 5 см

Converting to centimeters: 27 см = 27 cm 2 дм = 2 * 10 см = 20 cm 8 см = 8 cm 4 дм = 4 * 10 см = 40 cm 3 см = 3 cm 5 см = 5 cm

Now we can perform the addition: 27 cm + 20 cm + 8 cm + 40 cm + 3 cm - 5 cm

Adding the numbers: (27 + 20 + 8 + 40 + 3) cm - 5 cm 98 cm - 5 cm

Subtracting: 98 cm - 5 cm = 93 cm

Therefore, the result is 93 centimeters.
