Answer 1

Answer:

25/100*40=10 girl where glasses

Answer 2

Therefore 6 girls wear glasses.

Step-by-step explanation:

Given that the number students in a class is 40.

Girls make up 60% of the class.

Its means,

If there are 100 students in the class, then the number of girls is 60.

There are 1 students in the class, then the number of girls is $\frac{60}{100}$

There are 40 students in the class, then the number of girls is $\frac{60}{100} \times 40$

                                                                                                      =24

25% of the girls wear glasses.

It means,

Out of 100 girls, 25 girls wear glasses.

Out of    1   girls,   $\frac{25}{100}$   girls wear glasses.

Out of 24  girls,  $\frac{25}{100}\times 24$= 6   girls wear glasses.

Therefore 6 girls wear glasses.
