1. B forms a proportion, this is what I did, i simply 10/18 to 5/9 and i try to see if 5/9 is equivalent to 25/45 and it is. 5/9*5/5= 25/45
2. You multiply 27*4=108 then 108/12=9 so a=12
3. you multiply 16*21=336 then 336/12=28 so b=28
Hope this helps!
Number of people sat in each section on visitor side is equal to 468
<u>Solution:</u>
Given that
Total number of people went to football game = 8844
Also given 5,100 sat on the home side and the rest sat on the visitor'a side.
Means Number of people sat on the home side = 5100
And remaining Number of people sat on the visitor side = Total number of people went to football game - Number of people sat on the home side
= 8844 – 5100 = 3744
Also given people sitting on the visitor's side filled 8 equal-sized sections
Need to calculate people sat in each section that is number of people on side in 1 section.
As calculated , total number of people sitting in equally sized 8 sections on visitor side = 3744
=> number of people sitting in 1 section on visitor side = 
Hence 468 people sat on each section
That would be an independent variable.
Answer:
Suponiendo que te refieres a calcular el 28% de 375, tu respuesta es 105.
Step-by-step explanation:

y · 100 = 28 · 375
100y = 10500
100y ÷ 100 = 10500 ÷ 100
y = 105
