Answer 1

$\bold{\huge{\purple{\underline{ Solutions }}}}$

Solution (a) :-

$\bold{\dfrac{ 7}{6}}{\bold{ + }}{\bold{\dfrac{ 2}{5}}}$

• By taking LCM of the given denominators

$\sf{ = \:}{\sf{\dfrac{ 35 + 12 }{30}}}$

$\sf{ =\: }{\sf{\red{\dfrac{ 47 }{30}}}}$

Hence, The answer is 47/30

Solution ( b) :-

$\bold{\dfrac{ 1}{7}}{\bold{ + }}{\bold{\dfrac{ 1}{8}}}$

• By taking LCM of the given denominators

$\sf{ =\: }{\sf{\dfrac{ 8 + 7 }{56}}}$

$\sf{ =\: }{\sf{\red{\dfrac{ 15}{56}}}}$

Hence, The answer is 15/56

Solution ( c) :-

$\bold{\dfrac{ 7}{13}}{\bold{ + }}{\bold{\dfrac{ 5}{10}}}$

• By taking LCM of the given denominators

$\sf{=\:}{\sf{\dfrac{ 70 + 65 }{130}}}$

$\sf{ = \:}{\sf{\dfrac{ 135}{130}}}$

$\sf{ =\:}{\sf{\red{\dfrac{ 27}{26}}}}$

Hence, The answer is 27/26

Solution ( d) :-

$\bold{\dfrac{ 7}{5}}{\bold{ - }}{\bold{\dfrac{ 1}{3}}}$

• By taking LCM of the given denominators

$\sf{ =\:}{\sf{\dfrac{ 21 - 5 }{15}}}$

$\sf{ = \:}{\sf{\red{\dfrac{ 16}{15}}}}$

Hence, The answer is 16/15

Solution ( e) :-

$\bold{\dfrac{ 8}{7}}{\bold{ - }}{\bold{\dfrac{ 9}{11}}}$

• By taking LCM of the given denominators

$\sf{=\:}{\sf{\dfrac{ 88 - 63}{77}}}$

$\sf{=\:}{\sf{\red{\dfrac{ 25}{77}}}}$

Hence, The answer is 25/77

Solution ( f) :-

$\bold{\dfrac{ 11}{4}}{\bold{ - }}{\bold{\dfrac{ 1}{9}}}$

• By taking LCM of the given denominators

$\sf{=\:}{\sf{\dfrac{ 99 - 4}{36}}}$

$\sf{ =\: }{\sf{\red{\dfrac{ 95}{36}}}}$

Hence, The answer is 95/36
