Key Concepts
New Concept To perform division with a decimal divisor, we create an equivalent problem where the divisor is a whole number by shifting the decimal point.
To divide by a decimal number, we move the decimal point in the divisor to the right to make the divisor a whole number. Then we move the decimal point in the dividend the same number of places to the right. What’s next This is the foundational method. Next, you'll apply this technique in worked examples, from simple equations to practical word problems.
