8 0

Ok so ratios are poroportion

boys/total=boys/100
total=17+8=25
boys=17
17/25=boys/100
multiply both sides by 100
68=boys

68 boys

4 0

So the total number of students equals 8+17 = 25 students
Proportionally:
$\frac{17}{25} = \frac{x}{100}$

Thus,
$x = \frac{17*100}{25} = 68$ boys out of the 100 students.
