Question

Out of 50 students in the class 9 like football, 15 like cricket and remaining like tennis. Find the ratio of : (i) Number of students liking football to number of students liking tennis. (ii) Number of students liking cricket to total number of students.​

Answer 1

Answer:

[HCF of 12,30 = 6]

Step-by-step explanation:

number of students liking tennis = total number of students - [number of students liking football + number os students liking cricket]

number of students liking tennis = 30+ [6+12] = 12

i) number\ of\ students\ liking\ \frac{football}{tennis\ }=\ \frac{6\div6}{12\div6}=\frac{1}{2}

[HCF of 6,12=6]

ii) \frac{number\ of\ students\ liking\ cricket}{numberof\ students\ liking\ tennis}=\ \frac{12}{30\ }=\frac{12\div6}{30\div6}=\frac{2}{5}=2:5

[HCF of 12,30 = 6]
