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
Is 8 to 9 proportional to 3 to 4?
To determine if two ratios are proportional, we cross multiply and check if the products are equal. In this case, 8 * 4 = 32 and 9 * 3 = 27. Since 32 is not equal to 27, the ratios 8 to 9 and 3 to 4 are not proportional.
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
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

What is true about ratios for proportional relationships that is not true about ratios for other relationships?
For proportional relationships the ratio is a constant.
Is 8 to 9 proportional to 3 to 4?
To determine if two ratios are proportional, we cross multiply and check if the products are equal. In this case, 8 * 4 = 32 and 9 * 3 = 27. Since 32 is not equal to 27, the ratios 8 to 9 and 3 to 4 are not proportional.
Is the ratio of length to width for these two rectangles proportional?
To determine if the ratio of length to width for two rectangles is proportional, you need to compare the ratios of their lengths to widths. If the ratios are equal, then the rectangles are proportional. For example, if Rectangle A has a length of 10 units and a width of 5 units (ratio of 10:5 or 2:1), and Rectangle B has a length of 20 units and a width of 10 units (ratio of 20:10 or 2:1), then the rectangles are proportional because the ratios are equal.
Are 7 9 and 70 90 are proportional?
In order to determine if two sets of numbers are proportional, you need to compare their ratios. For 7 and 9, the ratio is 7/9, which simplifies to 0.777. For 70 and 90, the ratio is 70/90, which simplifies to 0.778. Since these two ratios are not equal, 7 and 9 are not proportional to 70 and 90.

Are the ratios 8 to 7 and 2 to 28 proportional?
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).
