Answer:

The correct answer is

2\frac{2}{9}

Step-by-step explanation:

Method 1

We want to simplify,

-2\frac{1}{9} -(-4\frac{1}{3})


The double negatives becomes positive,


=-2\frac{1}{9} +4\frac{1}{3}


We now add the whole number parts and the fractions separately


=-2+4-\frac{1}{9} +\frac{1}{3}


This will give us,

=2-\frac{1}{9} +\frac{1}{3}


The least common denominator for the fractional parts is 9.

=2+\frac{-1+3\times1}{9}


=2+\frac{-1+3}{9}


=2+\frac{2}{9}


=2\frac{2}{9}


Method 2

We want to simplify,

-2\frac{1}{9} -(-4\frac{1}{3})


The double negatives becomes positive,


=-2\frac{1}{9} +4\frac{1}{3}


We first convert the mixed numbers to improper fractions to obtain,


=-\frac{2\times9+1}{9} +\frac{4\times3+1}{3}


We carry out the multiplication in the numerator to get,


=-\frac{18+1}{9} +\frac{12+1}{3}


We add in the numerator to get,

=-\frac{19}{9} +\frac{13}{3}

The least common denominator is 9.

=\frac{-19+13\times3}{9}


=\frac{-19+39}{9}

=\frac{20}{9}

We convert back to mixed numbers to get,

=2\frac{2}{9}
