Calculation of People Continuing Grain Harvesting

To calculate the number of people continuing the grain harvesting, we'll follow the given information step by step.

1. Initial Situation: - 9 brigades with 12 people in each brigade were initially working on the grain harvesting.

2. Reallocation of Workers: - From the initial 9 brigades, 4 brigades with 18 people in each brigade were reassigned to other work.

Calculation:

To find out how many people continued the grain harvesting, we can calculate the total number of people in the initial 9 brigades and then subtract the total number of people reassigned to other work.

1. Total People Initially Working: - Total people in initial 9 brigades = 9 brigades * 12 people/brigade - Total people in initial 9 brigades = 108 people

2. Total People Reassigned: - Total people in reassigned 4 brigades = 4 brigades * 18 people/brigade - Total people in reassigned 4 brigades = 72 people

3. People Continuing Grain Harvesting: - People continuing grain harvesting = Total people initially working - Total people reassigned - People continuing grain harvesting = 108 people - 72 people - People continuing grain harvesting = 36 people

Therefore, 36 people continued the grain harvesting after the reallocation of workers.
