Answers
Answer:
Given, number of girls = 2300, and the total number of students = 4320
number of boys= number of students - number of girls
= 4320 - 2300 =2020
i) required ratio = \frac{number\ of\ gitls}{total\ number\ of\ students}=\ \frac{2300}{4320}=\frac{2300\div20}{4320\div20}=\frac{115}{216}=\ 115:216
total number of students
number of gitls
=
4320
2300
=
4320÷20
2300÷20
=
216
115
= 115:216
ii) required ratio =\frac{number\ of\ boys}{number\ og\ girls}=\frac{2020}{2300}=\frac{2020\div20}{2300\div20}=\frac{101}{115}=101:115
number og girls
number of boys
=
2300
2020
=
2300÷20
2020÷20
=
115
101
=101:115
ii) required ratio= number\ of\ \frac{boys}{students}=\frac{2020}{4320}=\frac{2020\div20}{4320\div20}=\frac{101}{216}=101:216number of
students
boys
=
4320
2020
=
4320÷20
2020÷20
=
216

Answer:
ven, number of girls = 2300, and the total number of students = 4320
number of boys= number of students - number of girls
= 4320 - 2300 =2020
i) required ratio = \frac{number\ of\ gitls}{total\ number\ of\ students}=\ \frac{2300}{4320}=\frac{2300\div20}{4320\div20}=\frac{115}{216}=\ 115:216
total number of students
number of gitls
=
4320
2300
=
4320÷20
2300÷20
=
216
115
= 115:216
ii) required ratio =\frac{number\ of\ boys}{number\ og\ girls}=\frac{2020}{2300}=\frac{2020\div20}{2300\div20}=\frac{101}{115}=101:115
number og girls
number of boys
=
2300
2020
=
2300÷20
2020÷20
=
115
101
=101:115
ii) required ratio= number\ of\ \frac{boys}{students}=\frac{2020}{4320}=\frac{2020\div20}{4320\div20}=\frac{101}{216}=101:216number of
students
boys
=

2020
=
