Answer 2

$\huge\red{1.}$

$let \: second \: rational \: no = x$

$\large{\frac{ - 3}{10} + x = \frac{ 3}{2}}$

$\large{x = \frac{3}{2} + \frac{3}{10}}$

$\large{x = \frac{15 + 3}{10}}$

$\large{x = \frac{18}{10}}$

$\huge\purple{\boxed{\pink{x = \frac{9}{5}}}}$

$\huge\red{2.}$

$5 + \frac{3}{5} - \frac{7}{10}$

$\large{= \frac{50 + 6 - 7}{10}}$

$\large{= \frac{49}{10}}$

$\huge\purple{\boxed{\pink{= 4.9}}}$
