Solution
The correct option is D 0.5 metres
Initial length of wood = 1.25 metres
Sawed length of wood = 0.75 metres
Final length of wood = 1.25 m - 0.75 m
Let's subtract:1.25−0.75:
Step 1: Align the decimal numbers according to their place values one below the other.
O . t h 1 . 2 5 − 0 . 7 5−−−−−−−
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 metres long now.
Initial length of wood = 1.25 metres
Sawed length of wood = 0.75 metres
Final length of wood = 1.25 m - 0.75 m
Let's subtract:1.25−0.75:
Step 1: Align the decimal numbers according to their place values one below the other.
