28/7= 4 49/7=7
4:7 <=== simplified ratio
I hope this helps!

For this case we have to define "y" directly with "x" when there is a constant of proportionality "k", such that:

This is known as direct variation.
On the other hand, if y varies inversely with x we have to:

This is known as inverse variation.
Answer:
, direct variation
5.7 x 10^8 is known as the scientific notation.Scientific notation is one way of showing a long number to a shorter one given with the followin choices, let's find out which one of those are correct:
=> 5.7 x 10^ 8
=> 5.7 x (10 x 10 x 10 x 10 x 10 x 10 x 10 x 10)
=> 5.7 * 100 000 000
=> 570 0000 000 or 5 hundred seventy milionThe correct answer is letter C. 570 000 000
