A carpenter bought a piece of wood that was 8.6 centimeters long. Then he sawed 0.9 centimeters off the end. How long is the piece of wood now?

Question

​
centimeters

Answer 1

To find the length of the piece of wood after the carpenter sawed off 0.9 centimeters, you can subtract the length that was sawed off from the original length.

Original length: 8.6 centimeters
Length sawed off: 0.9 centimeters

Now, perform the subtraction:

8.6 cm - 0.9 cm = 7.7 cm

Therefore, the length of the piece of wood now is 7.7 centimeters.
