How can you use a table to decide if a relationship is proportional?
If the ratio between each pair of values is the same then the relationship is proportional. If even one of the ratios is different then it is not proportional.
Determine whether the ratios 9 15 and 6 10 form a proportion Justify your answer?
The fractions are proportional and their cross products are equal
What are two equivalent ratios called?
They are said to be proportional.
How do you tell if a pair of ratios are proportional?
you have to times and get the answer correct or not
Are the ratios 16 to 18 and 18 to 24 proportional?
yes, they are.
How do you determine whether ratios are proportional?
you divide the numerator by the denominator, if you get the same to the other fractions, it is proportional. Another solution is if you reduce the two fractions to simplest form and they are the same, they are also proportional.
How can you use constant ratios to determine if a relationship is proportional?
set up a proportion and see if both sides simplify to the same answer. If the 2 ratios represent a constant ratio they will simplify into fractions

No.
What does it mean for ratios to be proportional?
Two ratios, a:b and c:d are proportional if there is some number x such that a = cx and b = dx. Equivalently, if ad = bc (each is equal to cdx).
Are the ratios 16 to 18 and 18 to 24 proportional?
