(a) Number of students who opted basketball to the number of students who opted table tennis.
(b) Number of students who opted cricket to the number of students opting basketball.
(c) Number of students who opted basketball to the total number of students
Answers
Answer:
Total number of students = 1800
Students opted basketball = 750
Students opted cricket = 800
Students opted table tennis -
= 1800 - (750 + 800)
= 1800 - 1550
= 250
Students opted tennis = 250
Finding Ratios -
Students who opted basketball : Students opted table tennis
750 : 250
Simplifying by 250
250 x 3 = 750
250 x 1 = 250
3 : 1
The Ratio is 3 : 1
Step-by-step explanation:
Given :
Total number of students = 1800
Students opted basketball = 750
Students opted cricket = 800
Students opted table tennis -
= 1800 - (750 + 800)
= 1800 - 1550
= 250
Students opted tennis = 250
