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

<h3><u>Solution </u><u>(</u><u>a)</u><u> </u><u>:</u><u>-</u></h3>

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

<u>By </u><u>taking </u><u>LCM </u><u>of </u><u>the </u><u>given </u><u>denominators </u>

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

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

Hence, The answer is 47/30

<h3><u>Solution </u><u>(</u><u> </u><u>b</u><u>) </u><u> </u><u>:</u><u>-</u></h3>

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

<u>By taking LCM of the given denominators </u>

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

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

Hence, The answer is 15/56

<h3><u>Solution </u><u>(</u><u> </u><u>c</u><u>) </u><u> </u><u>:</u><u>-</u></h3>

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

<u>By taking LCM of the given denominators </u>

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

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

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

Hence, The answer is 27/26

<h3><u>Solution </u><u>(</u><u> </u><u>d</u><u>) </u><u> </u><u>:</u><u>-</u></h3>

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

<u>By taking LCM of the given denominators</u>

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

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

Hence, The answer is 16/15

<h3><u>Solution </u><u>(</u><u> </u><u>e) </u><u>:</u><u>-</u></h3>

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

<u>By taking LCM of the given denominators</u>

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

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

Hence, The answer is 25/77

<h3><u>Solution </u><u>(</u><u> </u><u>f</u><u>) </u><u>:</u><u>-</u></h3>

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

<u>By taking LCM of the given denominators</u>

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

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

Hence, The answer is 95/36
