=5/3
=5:3
b)ratio of boys to total students=20/32
=5/8
=5:8
c)ratio of girls to total students=12/32
=3/8
=3:8
Answer:
a) 5:3 b) 5:8 c) 3:8
Step-by-step explanation:
a) Number of students = 32
Number of girls = 12
Number of boys = total number of students - number of girls
= 32 - 12 = 20
Since , ratio of number of boys to number of girls is
20/12 = 5/3
= 5:3
b) Number of students = 32
Number of boys = 12
Since ,the ratio of number of boys to Total number of students is
20/32 = 5/8
= 5:8
c) Number of students = 32
Number of girls = 12
Since, the ratio of number of girls to total number of students is
12/32 = 3/8
=3:8
