6.5A Ratio tables, scales, graphs

A ratio table is a table that shows the relationship between two quantities, where the ratios of the quantities are constant.

To determine the factor of change, divide each number by the previous number in the sequence.

The scale in a model is the ratio of a model's dimensions to the actual dimensions of the object it represents.

To set up a proportion, create a fraction that compares two ratios and set it equal to another fraction that compares the corresponding ratios.

The relationship can be expressed as a ratio, where 3 eggs correspond to 45 cookies, simplifying to 1 egg for every 15 cookies.

A scale factor is a number that scales, or multiplies, some quantity.

You can represent a ratio using a table by listing pairs of values that maintain the same ratio.

Models are used to represent and simplify complex real-life situations, making them easier to understand and analyze.

To convert a scale from inches to feet, divide the number of inches by 12, since there are 12 inches in a foot.

The formula is: Total items = (part/ratio) * total ratio.
