Front

What is the formula to find the total number of books if you have a certain number of books per unit and a number of units?

Front

How do you find the total number of limes if you have a certain number of boxes and each box holds a specific number of limes?

Back

Multiply the number of boxes by the number of limes each box holds. For example, if there are 45 boxes and each holds 100 limes, then Total Limes = 45 x 100 = 4500.

Front

Front

How do you express a relationship between two quantities using an equation?

Back

An equation shows that two expressions are equal. For example, if Oakdale's population is 856 and Grovetown's is 856 divided by 100, the equation is 856 = 100 x Grovetown's population.

Front

What does it mean if one number is '100 times' another number?

Back

It means that the first number is equal to the second number multiplied by 100. For example, if Grovetown's population is 8.56, then Oakdale's population is 8.56 x 100 = 856.
