Find the missing numbers:

(i) 3 glasses of juice shared equally among 4 friends is the same as _ glasses of juice shared equally among 8 friends.

So, $\dfrac{3}{4} = \dfrac{\boxed{\phantom{653}}}{8}$

(ii) 4 kg of sugar divided equally in 3 bags is the same as 12 kg of sugar divided equally in _ bags.

So, $\dfrac{4}{3} = \dfrac{12}{\boxed{\phantom{653}}}$

(iii) 7 gulabjamuns divided among 5 children is the same as gulabjamuns divided among children.

So, $\dfrac{7}{5} = \dfrac{\boxed{\phantom{653}}}{\boxed{\phantom{653}}}$

(i) $\dfrac{3}{4} = \dfrac{\boxed{\phantom{653}}}{8}$

To get 8 from 4, we have to multiply 4 by 2.

So, multiply numerator and denominator by 2.

$\Rightarrow \dfrac{3}{4} = \dfrac{3 \times 2}{4 \times 2} = \dfrac{6}{8}.$

Hence, the missing number is 6 i.e. 6 glasses of juice shared equally among 8 friends.

(ii) $\dfrac{4}{3} = \dfrac{12}{\boxed{\phantom{653}}}$

To get 12 from 4, we have to multiply 4 by 3.

So, multiply numerator and denominator by 3.

$\Rightarrow \dfrac{4}{3} = \dfrac{4 \times 3}{3 \times 3} = \dfrac{12}{9}.$

Hence, the missing number is 9 i.e. 12 kg of sugar divided equally in 9 bags.

(iii) $\dfrac{7}{5} = \dfrac{\boxed{\phantom{653}}}{\boxed{\phantom{653}}}$

We can multiply both numerator and denominator by 2.

$\Rightarrow \dfrac{7}{5} = \dfrac{7 \times 2}{5 \times 2} = \dfrac{14}{10}.$

Hence, the missing numbers are 14 and 10 i.e. 14 gulabjamuns divided among 10 children.
