The square root ones are correct though

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
svet-max [94.6K]
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.
