Quantity of rice required by a family in one month = 48 kg
Total number of people in the family = 8
Quantity of rice required by each person
= 48 ÷ 8
By repeated subtraction method
= 48 - 8 - 8 - 8 - 8 - 8 - 8 = 0
8 is subtracted 6 times.
48 ÷ 8 = 6
Thus, each person require 6 kg of rice each in a month.
