Esmerelda simplified a complex fraction. Her work is shown below. Negative 5 and one-fourth divided by three-halves = negative StartFraction 21 over 4 EndFraction divided by three-halves = (Negative StartFraction 21 over 4 EndFraction) (Three-halves) = Negative StartFraction 24 over 6 EndFraction = negative 4

Given:

The complex fraction is

Esmerelda simplified a complex fraction and steps are given.

To find:

The mistake of Esmerelda.

Solution:

We have,

Convert the mixed fraction in improper fraction.

Use the reciprocal of the divisor.

Therefore, the correct value of given fraction is .

Three mistakes of Esmerelda are:

1. Esmerelda added the numerators.

2. Esmerelda added the denominators.

3. Esmerelda did not use the reciprocal of the divisor.

step-by-step explanation:

if x = 2 you have to find x to finish the problem

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
