Step-by-step explanation:
We need to solve the given fractions.
(1) [tex]18\times \dfrac{2}{12}=3[/tex]
(2)
[tex]2\dfrac{2}{3}\times 2\dfrac{1}{4}\\\\=\dfrac{8}{3}\times \dfrac{9}{4}\\\\=6[/tex]
(3) [tex]\dfrac{3}{5}\div 9[/tex]
We know that, [tex]\dfrac{x}{y}\div \dfrac{a}{b}=\dfrac{x}{y}\times \dfrac{b}{a}[/tex]
So,
[tex]\dfrac{3}{5}\div 9=\dfrac{3}{5}\times \dfrac{1}{9}\\\\=\dfrac{1}{15}[/tex]
Hence, this is the required solution.
