Answer:
96:144
Step-by-step explanation:
Since there are 240 students and the known value is 96 students buying lunch, you simply subtract the two numbers.
240 - 96 = 144
There are 144 students bringing bag lunch.
The ratio is asking students purchasing lunch to students bringing a bag lunch, which would be 96:144
The simplified answer is 2:3
To get this, divide 144 by 96
This, in turn, would give you in answer of 3/2 which can be inversed to get the right answer
