Answer
$\frac{36}{63}=\frac{4}{7}=\frac{12}{21}$Solution:
$\frac{36}{63}=\frac{4}{\Box}=\frac{\Box}{21}$
$\frac{36}{63}=\frac{4}{\Box}$
$\therefore4=36\div9$
$\frac{36}{63}=\frac{36\div9}{63\div9}=\frac{4}{7}$
and $\frac{36}{63}=\frac{\Box}{21}$
$21=63+3$
$\therefore\frac{36}{63}=\frac{36\div3}{63\div3}=\frac{12}{21}$
$\therefore\frac{36}{63}=\frac{4}{7}=\frac{12}{21}$
$\frac{36}{63}=\frac{4}{\Box}=\frac{\Box}{21}$
$\frac{36}{63}=\frac{4}{\Box}$
$\therefore4=36\div9$
$\frac{36}{63}=\frac{36\div9}{63\div9}=\frac{4}{7}$
and $\frac{36}{63}=\frac{\Box}{21}$
$21=63+3$
$\therefore\frac{36}{63}=\frac{36\div3}{63\div3}=\frac{12}{21}$
$\therefore\frac{36}{63}=\frac{4}{7}=\frac{12}{21}$
