What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together. It expresses how much of one quantity corresponds to one unit of another quantity.

Front

How do you find the cost of multiple items when given the cost of a specific number of items?

Back

To find the cost of multiple items, first determine the cost per item (unit rate) by dividing the total cost by the number of items. Then, multiply the cost per item by the desired number of items.

Front

What is an equivalent ratio?

Back

Equivalent ratios are two or more ratios that express the same relationship between numbers. For example, the ratios 1:2 and 2:4 are equivalent.

Front

If 3 apples cost $9.99, how do you calculate the cost of 4 apples?

Back

First, find the cost per apple by dividing $9.99 by 3, which is $3.33. Then, multiply $3.33 by 4 to get $13.32.

Front

What is the ratio of red fish to blue fish if there are 20 blue fish and the ratio is 3:5?

Back

If the ratio of red fish to blue fish is 3:5, and there are 20 blue fish, then there are 12 red fish (3/5 = x/20, solving gives x = 12).

Front

How do you solve for missing numbers in equivalent ratios?

Back

To solve for missing numbers in equivalent ratios, set up a proportion and cross-multiply to find the unknown values.

Front

What is the formula to calculate total earnings based on a fixed earning rate?

Back

Total earnings can be calculated using the formula: Total Earnings = (Earnings per time period) x (Number of time periods).

Front

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

Back

To determine the unit rate, divide the total cost by the quantity. For example, if 4 gallons of milk cost $11, the unit rate is $11 ÷ 4 = $2.75 per gallon.

Front

What is the process to find the total cost of items when given a unit price?

Back

To find the total cost, multiply the unit price by the number of items. For example, if the unit price is $2.75 and you buy 4 items, the total cost is $2.75 x 4 = $11.

Front

How can you use a tape diagram to solve ratio problems?

Back

A tape diagram visually represents the parts of a ratio, helping to see the relationship between quantities and solve for unknowns.
