Question

22. In a class of 40 students,2/5 of the students are going to picnic.How many students are not going to the picnic?​

Answer 1

➤ Answer :-

Number of students going to picnic :-

$\longmapsto \sf \: \frac{2}{5} \: of \: 40$

$\longmapsto \sf \: \frac{2}{5} \times 40$

$\longmapsto \sf \cancel \frac{80}{5} = \frac{16}{1} = 16$

Now,

Number of students not going to picnic :-

Total students - Number of students going to picnic

$\longmapsto\sf\:40 - 16$

$\longmapsto\sf\:24 \: \: students$

$\Huge\therefore$24 students are not going to picnic.
