Setler [38]

Answer:

12 students

Step-by-step explanation:

Given

Students = 54

Required

Determine the number of students that eat lunch once a week

In Sets;

If out of 9, at least 7 eats one a week then

9 - 7 eats lunch once a week

9 - 7 = 2

<em>In other words;</em>

2 out of 9 students eat lunch once a week

Number of students in this category is then calculated as thus;

Number = \frac{2}{9} * 54

Number = \frac{2 * 54}{9}

Number = \frac{108}{9}

Number = 12
