The bag of rice

A shop counter with a balance scale that is perfectly level. On the left pan sits a closed sack of rice. On the right pan are another sack that is three-quarters full and a small weight. A girl behind the counter looks pleased.

Linh's family runs a small shop. The label has fallen off a bag of rice, so she puts it on the old balance scales to find its weight.

On the other side she puts three-quarters of an identical bag of rice, poured from another bag, plus a 3/4 kg weight. The scales balance perfectly.

How many kilograms does the full bag of rice weigh?

Type a number of kilograms.
