Marks: +1, -0

5\frac{1}{5} + 2\frac{3}{5} + 1\frac{2}{5}

= ?

$7\frac{4}{5}$
$8\frac{3}{5}$
$6\frac{2}{5}$
$9\frac{1}{5}$
None of these

Solution:

Concept:

To add mixed fractions, convert them into improper fractions with a common denominator.

Explanation:

5\frac{1}{5} = \frac{5 \times 5 + 1}{5} = \frac{26}{5}

2\frac{3}{5} = \frac{2 \times 5 + 3}{5} = \frac{13}{5}

1\frac{2}{5} = \frac{1 \times 5 + 2}{5} = \frac{7}{5}

Now add them:

\frac{26}{5} + \frac{13}{5} + \frac{7}{5} = \frac{26+13+7}{5} = \frac{46}{5}

Convert back to a mixed fraction:

\frac{46}{5} = 9\frac{1}{5}

Answer:

9\frac{1}{5}

, which is option D.
