Rates and Ratios

Define Ratio

• A comparison of two quantities by division.
• A statement that two ratios are equivalent.
• Two quantities with different units.
• A rate with a second quantity of 1 unit.

Define rate

• A scale that represents a larger or smaller object in 2D.
• Ratio with a second quantity of 1 unit.
• A ratio of 2 quantities with different units.
• 2 quantities are equal but use different units of measure.

Define unit rate

• 2 quantities are equal but use different units of measure.
• A rate with a second quantity of 1 unit.
• A scale that represents a larger or smaller object in 3D.
• A process that uses rates to convert measurements from one unit to another.

Define equivalent ratios

• Two ratios next to each other
• a ratio reduced to its lowest terms
• when numbers in a ratio are multiplied of divided by the same number to obtain another ratio
• The quantities that make up a ratio
