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
Are two ratios always equal to each other?
No but the equal ratios are called Equivalent Ratios.
What are ratios that are equal and simplify to the same ratio?
They are equivalent ratios.
Are two ratios sometimes equal to each other?
Yes the ratios are sometimes equal to each other.
When two or more ratios are equivalent?
When the cross-products of the two ratios are equal.

Ratios of equal quantities are called factors?
Ye they are called factors but there are all different kinds of factors to decide from. :) hehehe smiley
What is an proportion?
a proportion is a relation of four quantities such that the first divided by the second is equal to the third divided by the fourth. in other words, it is a way to find equal fractions or ratios.
Are two ratios always equal to each other?
No but the equal ratios are called Equivalent Ratios.
What is a comparison of two quantities with different units?
ratios
What does it mean if the cross products of two ratios are not equal?
The ratios are not equal.
What are ratios that are equal?
They are called equivalent ratios.
What is the difference between equal ratios and equivalent ratios?
To write equal ratios multiply both terms by the same number or divided both terms. For example, 2/ 9 is a ratio equal ratio will be 4/18. There is no difference between equal ratios and equivalent ratios.
What it means when two ratios are equal?
They are equivalent ratios
Ratios that compare quantities of different units are called?
Proportion (i think...)
How do you describe a proportion?
A proportion is a statement that two ratios are equal. It is often written as a fraction with an equal sign between the numerators and denominators of the ratios. Proportions are used to compare the relationship between different quantities.
What is a similarity ratio?
similarity ratios are ratios in which both the ratios are equal to each other
