Answer:
[tex]28[/tex]
Step-by-step explanation:
We have been given that there are thirty five students in the class and one fifth have hats.
The students who have no hats would be: [tex]1-\frac{1}{5}[/tex]
[tex]\frac{5}{5}-\frac{1}{5}[/tex]
[tex]\frac{5-1}{5}[/tex]
[tex]\frac{4}{5}[/tex]
Since there are 35 students, so [tex]\frac{4}{5}[/tex] of 35 will have no hats.
[tex]\frac{4}{5}\times 35[/tex]
[tex]4\times7[/tex]
[tex]28[/tex]
Therefore, 28 students do not have hats.
