from his house​

Answer 1

Answer:

$\Huge\mathfrak\red{answer}$

$\longrightarrow\Huge\mathfrak\blue{2\5 + 9\10 }$

$\longrightarrow\Huge\mathfrak\red{lcm \: of \: 5and10 = 10}$

$\huge\mathfrak\blue{so \: it \: will \: be \: \ \ 5 \div 10 \times 2 + 10 \div 10 \times 9 = 4 + 9 = 13}$

$\huge\mathfrak\blue{so \binom{4}{10} + \binom{9}{10} }$

$\longrightarrow\huge\mathfrak\green{ \binom{13}{10} }$
