Answer:
Step-by-step explanation:
7). Ratio of the students who name hockey as their favorite sport to hose who name basketball.
Ratio =
=
= 1 : 5
Option W is the answer.
8). Ratio of the students whose favorite sport is either baseball or soccer to the total students,
Ratio =
=
=
= 11 : 19
Option O is the answer.
9). Ratio of the students who prefer soccer, basketball, baseball or hockey to those who preferred another sport,
Students who prefer soccer, basketball, baseball or hockey = 8 + 5 + 3 + 1 = 17
Students who prefer another sport = 2
Ratio = 17 : 2
Option K is the answer.
10). Ratio of total number of students to the students who preferred a sport with round ball,
Ratio =
= 2 : 17
Option P is the answer.
