Unit Rates

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

To calculate the unit rate, divide the total cost by the quantity. For example, if the total cost is $79.80 for 6 hours, the unit rate is $79.80 ÷ 6 = $13.30 per hour.

Divide the total number of slices by the number of pizzas: 40 slices ÷ 5 pizzas = 8 slices per pizza.

The formula is: Price per item = Total price ÷ Number of items.

The unit cost per pizza is calculated by dividing the total cost by the number of pizzas: $97.50 ÷ 15 = $6.50 per pizza.

To find the price per gallon, divide the total cost by the number of gallons: Total cost ÷ Gallons = Price per gallon.

The unit price is calculated by dividing the total cost by the number of candy bars: $13.50 ÷ 9 = $1.50 per candy bar.

Understanding unit rates helps consumers make informed decisions about purchases, compare prices, and evaluate costs effectively.

Unit rates are a specific type of ratio that compares a quantity to one unit of another quantity, simplifying the comparison.

Unit rates can help in budgeting by allowing individuals to compare costs per item or service, helping to allocate funds more effectively.
