## What is it called when you compare two quantities?

Ratio – A comparison of two quantities by division. Equivalent Ratio – ratios the express the same relationship between two quantities. Rate – A ratio comparing two quantities with different kinds of units.

## What do you mean by ratio?

In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3).

**What is a relationship between two quantities?**

Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

### What is difference between ratio and proportion?

A ratio is a comparison of two quantities. A proportion is an equality of two ratios.

### Is the quality of two ratios?

When two ratios are equal, the mathematical statement of that equality is called a proportion. If is equal to , then is called a proportion. To find out if two ratios form a proportion, one can evaluate the cross product. If and are ratios, then the two ratios form a proportion if ad = bc.

**What is a Comparing ratio?**

What does a Comparison of Ratio Mean? Comparison of ratios means comparing the relationship between two or more ratios. The quantitative relationship of two amounts or numbers is called ratio and when 3 or more quantities come into play, a comparison of ratios is necessary.

#### Is the relationship between the two quantities linear?

A linear relationship between two quantities will produce a graph of a straight line. The line represents every possible solution for the range of the function. In order to create the line, we use the function equation and evaluate the range, or output, values based upon several of the domain, or input, values.

#### How do you know if a relationship between two quantities is linear?

A linear relationship can also be found in the equation distance = rate x time. Because distance is a positive number (in most cases), this linear relationship would be expressed on the top right quadrant of a graph with an X and Y-axis.
