SOLUTION:

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

ii) required ratio =\frac{number\ of\ boys}{number\ og\ girls}=\frac{2020}{2300}=\frac{2020\div20}{2300\div20}=\frac{101}{115}=101:115

ii) required ratio= number\ of\ \frac{boys}{students}=\frac{2020}{4320}=\frac{2020\div20}{4320\div20}=\frac{101}{216}=101:216

"Please welcome video more creating brush number 10, which is in a college out of for 320 students. That means the total number of students is 4320 2300 girls. So 2300 of Earth's first of all, let's find several boys, which is the direct subject number of goals in the total number 0 0 2 0 2 0 for 2 and 2020 are the number of boys in the school. Because let's write this information on the ends writes it up here. They go further like that. Now the first question internet of course is the number of points to the total number of students. The answer would be 4 so the answer will be 2,300 2,300 / 4320. So let's first will cancel out the zeros after simplifying this your answer will come out to be the second 115 is to 12 x 115 just divided by 2 will get that answer. So when the Institute is you answer the question. It's one of the second parts. The second part is the number of boys to the number of birds number of boys is Founders 2020 the number of girls which was 2 which is 2 3 double zero again cancel. The zeros will be 115. This will become 1 0 1 so your answer is 101 is 2115. 101 101 is 211. Let's move on to the C1 or the last one. So the last one is the total number of boys to the number of students. So 2020 / for 320 yards after sintering. It will be 2 0 2 by 4 3 2 0 1 0 1 by 2. So I'm not to do the last thank you guys for watching the video. If you have any more doubts, please post in the comment section. Also, please like the video and subscribe to my channel. Thank you so much."
