(3) Number and operations. The student applies mathematical process standards to represent addition, subtraction, multiplication, and division while solving problems and justifying solutions. The student is expected to:

• (A) recognize that dividing by a rational number and multiplying by its reciprocal result in equivalent values;

• (B) determine, with and without computation, whether a quantity is increased or decreased when multiplied by a fraction, including values greater than or less than one;

• (C) represent integer operations with concrete models and connect the actions with the models to standardized algorithms;

• (D) add, subtract, multiply, and divide integers fluently; and

• (E) multiply and divide positive rational numbers fluently.
