Answer:
[tex]\frac{2}{5}[/tex] left
Step-by-step explanation:
Total the number of counters given out, that is
35 + 130 + 75 = 240
Subtract this from 400 to find the amount left
400 - 240 = 160 ← amount left
The fraction left is calculated as
[tex]\frac{left}{total}[/tex] = [tex]\frac{160}{400}[/tex] = [tex]\frac{16}{40}[/tex] = [tex]\frac{2}{5}[/tex]
