Question

OUT OF 32 STUDENTS IN A CLASS, 5 SAID THEY RIDE THEIR BIKES TO SCHOOL.  BASED ON THESE RESULTS, HOW MANY OF THE 800 STUDENTS IN THE SCHOOL RIDE THEIR BIKES TO SCHOOL?

Answer 1

Let, the total number of students in school that ride the bike to school be "x"
Now,
Using ratio and proportion, we get,
$\frac{5}{32} = \frac{x}{800}$

$\frac{5}{32}*800 = \frac{x}{800} *800$

$\frac{4000}{32} =x$

$125 =x$

$x=125$

So, out of 800 students, 125 ride their bike to school.
