If 4 bags can hold $\frac{1}{2}$ kg of rice, then how many kgs of rice can 48 bags hold?

Given, 4 bags can hold $\frac{1}{2}$ kg of rice.

$\therefore$ Amount of rice in 1 bag = $\frac{1}{2}\times \frac{1}{4}$ $=\frac{1}{8}$ kg
So, Amount of rice in 48 bags = $\frac{1}{8}\times 48=6$ kg

Hence, 48 bags can hold 6 kg of rice.
