Are the ratios 3 to 7 and 6 to 14 proportional?
They are equivalent.
How do you determine if the quantities in a pair of ratios are equivalent?
If the cross-product are equal the ratios are equal. Thus, a/b = c/d if (and only if) ad = bc
What is equivalent ratios in math?
They are quantities that have the same values as for example 3/4 is the same as 6/8
What are ratios of equal quantities?
The ratio of two equal quantities is 1 .
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).
What are two equivalent ratios called?
They are said to be proportional.
Are the ratios 3 to 7 and 6 to 14 proportional?
They are equivalent.
What is compound proportion?
Compound proportion refers to a mathematical relationship between two ratios where multiple quantities are compared. It involves comparing multiple ratios involving more than two quantities in a proportional relationship.
How are equivalent ratios like equivalent fractions?
Equivalent ratios are like equivalent fractions because they represent the same relationship between quantities in different forms. Just like equivalent fractions are different expressions of the same value, equivalent ratios show the same comparison between two quantities using different numerical values.

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.
What expresses the same relationship between two quantities?
A straight line graph - is one possible answer.
What term is used to mean that the sides were reduced at the same rate making two equivalent ratios?
The two sides are proportional.
what ratios can you use to determine whether the relationship is proportional?
look at the ratios and multiply
What are ratios of equal quantities?
The ratio of two equal quantities is 1 .
What are the ratios that name the same comparison?
equivalent ratios are different ratios that name the same comparison
