Answer 1

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

$( \frac{1}{10} - \frac{1}{20} ) \div 30 \times (5 + \frac{1}{5} )$

=>L.C.M of 10 and 20 is 20 & L.C.M of 5+1/5 is 5

$= > ( \frac{2 - 1}{20} ) \div 30 \times ( \frac{25 + 1}{5} )$

$= > \frac{1}{20} \times \frac{1}{30} \times \frac{26}{5}$

$= > \frac{26}{20 \times 30 \times 5}$

$= > \frac{26}{600 \times 5} = \frac{26}{3000} = \frac{13}{1500}$

$= > \frac{26}{20 \times 30 \times 5}$

$= > \frac{26}{600 \times 5} = \frac{26}{3000} = \frac{13}{1500}$
