Answer:
The last one
Step-by-step explanation:
You just have to find the percentage of each
First find the total
300+320+500+510=1630
1)freshman: (320÷1630)×100
2) sophomore:(300÷1630)×100
3) juniors:(500÷1630)×100
4)seniors:(510÷1630)×100
D) 18 freshman, 18 sophmores, 30 juniors, 30 seniors
ratio given:
320 : 300 : 500 : 510
320 = 300 and 500 = 510
therefore ratio of 300 : 300 : 500 : 500
Ratio of 300 : 500 = 18 : 30
18 : 18 : 30 : 30
