Answer 2

➤ Answer :-

$\tt \longrightarrow \dfrac{17}{3} + \dfrac{21}{5}$

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

LCM of 3 and 5 is 15.

$\tt \longrightarrow \dfrac{17 \times 5}{3 \times 5} + \dfrac{21 \times 3}{5 \times 3}$

$\tt \longrightarrow \dfrac{85}{15} + \dfrac{63}{15} = \dfrac{85 + 63}{15}$

$\tt \longrightarrow \dfrac{148}{15} = 9 \dfrac{13}{15}$

$\Huge\therefore$The answer is $\tt 9 \dfrac{13}{15}$

$\dashrightarrow \sf$Remember :-

• If the rational number is in mixed fraction, convert them to improper fractions to add or subtract.
• If the rational number is in unlike fraction, convert them into like fractions by taking the LCM of denominators.
• If the rational numbers are like fractions, we can add or subtract directly.
