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).
Equivalent ratios are often referred to as "proportional ratios." These are ratios that express the same relationship between two quantities, even though the numbers may differ. For example, the ratios 1:2 and 2:4 are equivalent because they represent the same proportional relationship.
Yes
They are equivalent.
To determine if two ratios form a proportion, you can use cross-multiplication. If the cross-products of the ratios are equal, the ratios are proportional. For example, for the ratios ( \frac{a}{b} ) and ( \frac{c}{d} ), if ( a \times d = b \times c ), then the two ratios form a proportion. Additionally, you can also compare the decimal values of the ratios; if they are equal, they are proportional.
To determine if a situation is a proportional relationship, you can compare rates by calculating the ratio of two quantities. If the ratios remain constant across different pairs of values, the relationship is proportional. For example, if increasing the number of items consistently results in a proportional increase in total cost, the situation is proportional. Conversely, if the ratios change, the relationship is not proportional.
For proportional relationships the ratio is a constant.
look at the ratios and multiply
The two sides are proportional.

They are said to be proportional.
No.
you have to times and get the answer correct or not
