Give your little one some practice building subtraction skills with this subtract whole number and decimal less than 10 worksheet. To ensure that each decimal has the same number of digits while subtracting decimals, students align the decimal points and insert additional zeros to the right of the number. Students then subtract digits at each place to find the difference. In this worksheet, numbers are laid one on top of another (vertical format). This encourages students to use the inherent place value structure to solve the problems.
