Question

A carpenter bought a piece of wood that was 1.25 metres long. Then she sawed 0.75 metres off the end. How long is the piece of wood now?
meters

Answer 1

Initial length of wood = 1.25 meters
Sawed length of wood = 0.75 meters

Final length of wood = 1.25 meters- 0.75 meters

$\text{Let's subtract}:1.25-0.75:$

Step 1: Align the decimal numbers according to their place values one below the other.
$O.th1.25-0.75-------$

Step 3: Subtract the numbers in the column from the right.

If needed, borrow a group of ten from the column to the left
Finally, place the decimal point of the sum vertically below the other decimal points.

The piece of wood is 0.5 meters long now.
