Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities where one of the quantities is expressed as a quantity of one. For example, if Ernie travels 195 miles in 3 hours, his unit rate is 65 miles per hour.

Front

How do you find the total distance traveled at a constant speed?

Back

To find the total distance traveled at a constant speed, multiply the speed (unit rate) by the time traveled. For example, if the speed is 65 miles per hour and the time is 5 hours, the distance is 65 x 5 = 325 miles.

Front

What is a ratio?

Back

A ratio is a relationship between two numbers that shows how many times the first number contains the second. For example, the ratio of dimes to nickels is 2 to 1.

Front

How do you simplify a ratio?

Back

To simplify a ratio, divide both terms of the ratio by their greatest common divisor (GCD). For example, the ratio of 10 dimes to 5 nickels simplifies to 2 to 1.

Front

What is a unit price?

Back

A unit price is the cost per single unit of a product, allowing for comparison between different products. For example, if Sargento cheese slices cost $2.48 for 10 slices, the unit price is $2.48 / 10 = $0.248 per slice.

Front

How do you calculate the unit price?

Back

To calculate the unit price, divide the total price by the number of units. For example, for Velveeta cheese slices costing $3.18 for 12 slices, the unit price is $3.18 / 12 = $0.265 per slice.

Front

What is the better deal when comparing unit prices?

Back

The better deal is the product with the lower unit price. In the example, Sargento has a unit price of $0.248 per slice, while Velveeta has $0.265 per slice, making Sargento the better deal.

Front

What is the formula for distance?

Back

The formula for distance is Distance = Speed x Time. This formula helps calculate how far an object travels over a period of time.

Front

What does it mean to travel at a constant speed?

Back

Traveling at a constant speed means moving at the same rate without speeding up or slowing down. For example, if Ernie travels 65 miles per hour consistently, he is traveling at a constant speed.

Front

How do you express a ratio in different forms?

Back

A ratio can be expressed in several forms, such as 'a to b', 'a:b', or 'a/b'. For example, the ratio of 2 to 1 can be written as 2:1 or 2/1.
