G6 Rate and Unit Rate Practice for the Assessment

Front

What is a rate?

Back

A rate is a ratio that compares two different quantities, often expressed as a fraction. For example, speed is a rate that compares distance to time.

Front

What is a unit rate?

Back

A unit rate is a rate in which the second quantity is one. It tells you how much of one item you get for one unit of another item.

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, if a 2lb bag of rice costs $3.06, the unit price is $3.06 ÷ 2 = $1.53 per pound.

Front

If a car travels 540 miles in 9 hours, what is its speed in miles per hour?

Back

Speed = Distance ÷ Time. So, 540 miles ÷ 9 hours = 60 miles per hour.

Front

How do you convert cups to quarts?

Back

To convert cups to quarts, divide the number of cups by 4, since there are 4 cups in 1 quart.

Front

What is the best value when comparing rates?

Back

The best value is the option with the lowest unit price or cost per item.

Front

If 8 pens cost $12.80, what is the unit price per pen?

Back

Unit price = Total price ÷ Number of items. So, $12.80 ÷ 8 = $1.60 per pen.

Front

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

Back

Total distance = Speed × Time. If a car travels at 60 mph for 4 hours, the distance is 60 × 4 = 240 miles.

Front

What is the formula for calculating unit price?

Back

Unit Price = Total Price ÷ Number of Units.

Front

If a recipe requires 8 cups of water, how many quarts do you need?

Back

8 cups = 8 ÷ 4 = 2 quarts.
