$\Large{\underbrace{\sf{\orange{Required\:Solution:}}}}$

(i) $\displaystyle{\bf{ \dfrac{5}{6} + \dfrac{-2}{5} - \dfrac{-2}{15}}}$

Sol'n. $\displaystyle{\rm{ \dfrac{5}{6} + \dfrac{-2}{5} - \dfrac{-2}{15}}}$

• L.C.M(Lowest common factor) of the denominators 6,5 and 15 is 30.
• Multiply the denominator of each term with a number results 30 and multiply the same number with their numerator also.

$\longrightarrow{\rm{ \dfrac{5\times 5 + (-2)\times 6 - (-2)\times 2}{30}}}$

• Simplify this

$\longrightarrow{\rm{ \dfrac{25+(-12)-(-4)}{30}}}$

$\longrightarrow{\rm{\dfrac{25-12+4}{30}}}$

$\longrightarrow{\rm{\dfrac{29-12}{30}}}$

$\large\implies{\boxed{\bf{\orange{\dfrac{17}{30}}}}}$

(ii) $\displaystyle{\bf{ \bigg( \dfrac{8}{5}\times \dfrac{-3}{2} \bigg) + \bigg( \dfrac{-3}{10} \times \dfrac{11}{16}\bigg)}}$

Sol'n. $\displaystyle{\rm{ \bigg( \dfrac{8}{5}\times \dfrac{-3}{2} \bigg) + \bigg( \dfrac{-3}{10} \times \dfrac{11}{16}\bigg)}}$

• Simplify this.

$\longrightarrow{\rm{ \bigg( \dfrac{-24}{10}\bigg) + \bigg( \dfrac{-33}{160}\bigg)}}$

$\longrightarrow{\rm{ \dfrac{-24\times16 - 33}{160}}}$

$\large\implies{\boxed{\bf{\orange{\dfrac{-417}{160}}}}}$
