Answer 2

➤ Answer :-

${ \tt \longrightarrow - 2 \dfrac{1}{3} + 4 \dfrac{3}{5} }$

Convert them into improper fractions so that the calculation becomes very easy.............

${ \tt \longrightarrow \dfrac{( - 7)}{3} + \dfrac{23}{5} }$

Convert them into like fractions by taking the LCM of the denominators i.e, 3 and 5.

LCM of 3 and 5 is 15.

${ \tt \longrightarrow \dfrac{( - 7) \times 5}{3 \times 5} + \dfrac{23 \times 3}{5 \times 3} }$

${ \tt \longrightarrow \dfrac{( - 35)}{15} + \dfrac{69}{15} = \dfrac{( - 35) + 69}{15} }$

$\tt \longrightarrow \dfrac{34}{15} = 2 \dfrac{4}{15}$

$\Huge\therefore$The answer is $\tt 2 \dfrac{4}{15}$ .
