instead of counting from the right. Evaluating the quotient of decimal numbers by the method of removing decimal points. Using two different factors (multiples of 10) to multiply the numerator and denominator. Conceptual Thinking that the decimals of numerator and denominator are independent numbers Adding fractions with different denominators Choosing the smallest multiple of denominators to be the LCM Conceptual Associating the term ‘Lowest’ as it appears in the abbreviation LCM to mean just a ‘small’ multiple. Dividing fractions reciprocals of both multiplicand and multiplied Adding or subtracting numerators and denominators separately. Procedural i.
