Answer 1

${\huge{\bold{\pink{\bigstar{\boxed{\boxed{\sf{AnSwer:-}}}}}}}}$

$\\ \sf\longmapsto8a + \dfrac{12}{280} = \dfrac{1}{10}$

$\\ \sf\longmapsto 8a + \dfrac{3}{70} = \dfrac{1}{10}$

$\\ \sf\longmapsto 8a = \dfrac{1}{10} - \dfrac{3}{70}$

$\\ \sf\longmapsto 8a = \dfrac{7 - 3}{70}$

$\\ \sf\longmapsto8a = \dfrac{4}{70}$

$\\ \sf\longmapsto \:8a = \dfrac{2}{35}$

$\\ \sf\longmapsto4a = \dfrac{1}{35}$

$\large{\underline{\boxed{\mathcal{\longmapsto \: a = \dfrac{1}{140}}}}}$

$Solve\: 8a +\dfrac{12}{280}= \dfrac{1}{10}$

${\huge{\bold{\purple{\bigstar{\boxed{\boxed{\bf{Question}}}}}}}}$

$8a +\dfrac{12}{280}= \dfrac{1}{10}$

$8a +\dfrac{3}{70}= \dfrac{1}{10}$

$8a = \dfrac{1}{10} - \dfrac{3}{70}$

$8a = \dfrac{7-3}{70}$

$8a = \dfrac{4}{70}$

$a = \dfrac{\cancel4}{70 \times \cancel 8_2}$

$a = \dfrac{1}{140}$
