[tex]1. \: \displaystyle \frac{3}{7} \times \frac{1}{7} = \boxed{\frac{3}{49}}[/tex]

[tex]\begin{aligned}\displaystyle 2) \: \frac{2}{5} \times 3\frac{2}{3} &= \frac{2}{5} \times \frac{11}{3}\\& = \dfrac{22}{15}\\& = \boxed{1\dfrac{7}{15}}\end{aligned}[/tex]

[tex]\begin{aligned}3) \: \displaystyle 2\frac{5}{6} \times 4\frac{1}{2} & = N\\\displaystyle \frac{17}{2} \times \frac{3}{2} & = N\\\dfrac{51}{4} & = N\\\boxed{12\dfrac{3}{4}} & = N\end{aligned}[/tex]

[tex]\begin{aligned}4) \: \displaystyle 4\frac{1}{2} \times \frac{1}{6} & = \frac{9}{2} \times \frac{1}{6}\\ & = \dfrac{9}{12} \: kg\\ & = \boxed{\dfrac{3}{4} \: kg}\end{aligned}[/tex]

[tex]\begin{aligned}5) \: \displaystyle 12\frac{1}{3} \times \frac{1}{5} & = \frac{37}{3} \times \frac{1}{5}\\ & = \dfrac{37}{15} \: ft\\ & = \boxed{2\dfrac{7}{15} \: ft.}\end{aligned}[/tex]
