What is a ratio of two quantities that have different units?
It is a rate. For instance, if the quantities are 10 km and 2 hours, then the ratio (10 km)/(2 hours) = 10/2 km/hour = 5 km/h, which is a rate of speed.
What is a ratio between 2 different quantities?
A ratio between two (usually) different quantities is the rate. Usually used to describe something compared to a quantity of time.
Why is 2 and 8 called a constant rate?
In the context of mathematics, a constant rate refers to a consistent relationship between two quantities. When we say that 2 and 8 represent a constant rate, it means that for every increase of 2 units in one quantity, there is a corresponding consistent increase of 8 units in another. This relationship can be expressed as a ratio (2:8), which simplifies to 1:4, indicating that the rate remains the same regardless of the specific values being considered.
What is the constant value of of the ratio of 2 proportional quantities?
The constant value of the ratio of two proportional quantities is known as the constant of proportionality. It represents the relationship between the two quantities, meaning that as one quantity changes, the other changes in a consistent manner. Mathematically, if ( y ) is proportional to ( x ), then this can be expressed as ( y = kx ), where ( k ) is the constant of proportionality. This constant remains the same regardless of the values of ( x ) and ( y ).
Which set of values describes two quantities that are in a proportional relationship?
Two quantities are in a proportional relationship if they maintain a constant ratio or rate. For example, if you have the values (2, 4) and (3, 6), the ratio of the first quantity to the second is the same for both pairs: 2:4 simplifies to 1:2, and 3:6 also simplifies to 1:2. Thus, any pair of values that can be expressed as k times the other (where k is a constant) indicates a proportional relationship.

What is a relationship in which the ratio of two variable quantities is constant in math?
In mathematics, a relationship in which the ratio of two variable quantities is constant is known as a direct variation. This means that as one variable increases or decreases, the other variable changes in a proportional manner. It can be represented by the equation ( y = kx ), where ( k ) is a constant. For example, if ( k = 2 ), then for every increase of 1 in ( x ), ( y ) will increase by 2.
Ratio that compares 2 quantities measured in different units?

What is a constant ratio?
A constant ratio refers to a fixed relationship between two quantities, where the ratio remains the same regardless of changes in the values of those quantities. For example, if the ratio of two variables, such as length and width, is always 2:1, it means that for every unit increase in width, length will increase by two units, maintaining the same proportion. This concept is commonly used in mathematics, finance, and physics to describe proportional relationships.
What does a unit rate look like?
A unit rate is a ratio that compares two quantities, with one of the quantities equaling 1. For example, if you drive 60 miles in 2 hours, the unit rate would be 30 miles per hour, indicating the distance traveled per each hour.
Is a rate a ratio always or never true?
A rate is a type of ratio that expresses the relationship between two quantities with different units, such as speed (miles per hour) or price per item. While all rates are ratios, not all ratios are rates, as some ratios compare quantities of the same unit (like 4 apples to 2 apples). Therefore, it’s accurate to say that a rate is always a ratio, but the reverse is not true.
Is there a silver ratio if there's a golden ratio?
yes, if the golden ratio is ((square root 5) +1)/2, then the silver ratio is (square root 2) +1. as the golden ratio is represented by phi, the silver ratio is represented by deltas. as two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one, two quantities are in the silver ratio if the ratio between the sum of the smaller plus twice the larger of those quantities and the larger one is the same as the ratio between the larger one and the smaller.
What makes 2 quantities proportional?
Two quantities are proportional if they maintain a constant ratio to each other, meaning that when one quantity changes, the other changes in a consistent way. This relationship can be expressed mathematically as ( y = kx ), where ( k ) is the constant of proportionality. If you can multiply or divide one quantity to obtain the other without altering the ratio, they are proportional. For example, if doubling one quantity results in the doubling of the other, they are proportional.
