Evaluating Esmerald's simplified expression, the errors in her evaluation are :

  • Esmerelda did not use the reciprocal of the Divisor.

  • Esmerelda added the numerator

  • Esmerelda added the denominator

The appropriate evaluation procedure should be :

[tex]\frac{-5\frac{1}{4}}{\frac{3}{2}}[/tex]

Convert the Numerator to an improper fraction

[tex]\frac{\frac{21}{4}}{\frac{3}{2}}[/tex]

Take the reciprocal of the denominator

[tex]\frac{3}{2} = \frac{2}{3} [/tex]

Multiply the Numerator by the reciprocal of the denominator

[tex](-\frac{21}{4} )(\frac{2}{3}) = - \frac{42}{12} = -3 \frac{1}{2}[/tex]

Therefore, Esmeralda made three errors in her simplification procedure.
