7/8

Answer 2

Answer:

$\frac{6}{12} + \frac{3}{8} \\ = \frac{ _{1 \: \: \: } \cancel 6}{ _{2 \: \: \: } \cancel{ 12}} + \frac{3}{8} \\ = \frac{1}{2} + \frac{3}{8} \\ = \frac{4 + 3}{8} \\ \boxed{ = \underline{ \underline{ \large \bf \frac{7}{8} }}} \\ \\ \frac{ - 2}{15} + \frac{7}{30} \\ = \frac{ - 4 + 7}{30} \\ = \frac{ \cancel 3 _{ \: \: \: 1}}{ \cancel{ 30} _{ \: \: \: 10} } \\ \boxed{ = \underline{ \underline{ \large \bf \frac{1}{10} }}}$
