Find the sum:
$- 2 \frac{1}{3} + 4 \frac{3}{5}$

Open in App

Solution

$- 2 \frac{1}{3} + 4 \frac{3}{5} = \frac{- 7}{3} + \frac{23}{5} = \frac{- 7 \times 5}{3 \times 5} + \frac{23 \times 3}{5 \times 3} [L.C.M of 3 and 5 is 15] = \frac{- 35}{15} + \frac{69}{15}$

$= \frac{- 35 + 69}{15} = \frac{34}{15} = 2 \frac{4}{15}$
