Unit Rate

Front

What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity, often expressed as 'per' something (e.g., miles per hour, cost per item).

Front

How do you calculate the unit rate from a total cost and quantity?

Back

To calculate the unit rate, divide the total cost by the number of items. For example, if 9 tickets cost $279, the unit rate is $279 ÷ 9 = $31 per ticket.

If a store has 120 customers in 8 hours, how do you find the unit rate in customers per hour?

Back

To find the unit rate, divide the total number of customers by the total hours. Here, 120 customers ÷ 8 hours = 15 customers per hour.

What is the unit rate if a pump moves 42 gallons in 7 minutes?

Back

To find the unit rate, divide the total gallons by the total minutes. Thus, 42 gallons ÷ 7 minutes = 6 gallons per minute.

Front

How do you determine the number of items per unit from a total number of items and containers?

Back

To find the number of items per container, divide the total number of items by the number of containers. For example, 55 seeds in 11 pots means 55 ÷ 11 = 5 seeds per pot.

Front

What is the unit rate if a store has 120 customers in 6 hours?

Back

To find the unit rate, divide the total number of customers by the total hours. Here, 120 customers ÷ 6 hours = 20 customers per hour.

Front

Why is understanding unit rates important in real-life applications?

Back

Understanding unit rates helps in making informed decisions, such as comparing prices, understanding speeds, and evaluating efficiency.

Front

What is the formula for calculating unit rate?

Back

The formula for calculating unit rate is: Unit Rate = Total Quantity / Number of Units.

Front

Can unit rates be expressed in different units? Give an example.

Back

Yes, unit rates can be expressed in different units. For example, speed can be expressed as miles per hour or kilometers per hour.

Front

How can you use unit rates to compare two different options?

Back

You can compare two options by calculating the unit rate for each and determining which option offers a better value (lower cost per item, higher speed, etc.).
