Picture relating to the question is attached below :
Answer:
Esmerelda did not use the recipro al of the Divisor.
Esmerelda added the numerator
Esmerelda added the denominator
Explanation:
Esmerelda's work:
-5 1/4 ÷ 3/2= -21/4 ÷3/2 = (-21/4)(3/2) = -24/6 = - 4
Esmerelda's errors:
When changing the quotient sign to multiplication ; the reciprocal of the denominator should be used to divide the numerator :
Hence,
-21/4 ÷3/2 = (-21/4)(3/2) (wrong expression)
-21/4 ÷3/2 = (-21/4)(2/3) (correct expression)
Also,
(-21/4)(3/2) = -24/6 ( wrong simplification)
The bracket symbol indicates multiplication. Hence, the values should be multiplied. The two Numerator values and the two denominator values.
