3 indira finds that on a typical day, 4 out of every 5 students at her school eat a cafeteria lunch. the rest of the students bring their lunch from home. indira’s school has 495 students. on a typical day, how many students at her school bring their lunch from home? show your work.
Answer
Explanation:
Step1: Find the fraction of students bringing lunch from home
The fraction of students eating cafeteria lunch is $\frac{4}{5}$, so the fraction of students bringing lunch from home is $1 - \frac{4}{5}=\frac{1}{5}$.
Step2: Calculate the number of students bringing lunch from home
Multiply the total number of students (495) by the fraction of students bringing lunch from home ($\frac{1}{5}$). So, $495\times\frac{1}{5} = \frac{495}{5}=99$.
Answer:
99
