3.2: Homemade Jams

Draw a diagram and write a multiplication equation to represent each situation. Then answer the question.

Mai had 4 jars. In each jar, she put 21/4 cups of homemade blueberry jam. Altogether, how many cups of jam are in the jars?

Priya filled 5 jars, using a total of 71/2 cups of strawberry jam. How many cups of jam are in each jar?

Han had some jars. He put 3/4 cup of grape jam in each jar, using a total of 63/4 cups. How many jars did he fill?

Here is an applet to use if you choose to.

[Scroll to the tool under "3.2: Homemade Jams"]

The toolbar includes buttons that represent 1 whole and fractional parts, as shown here. Click a button to choose a quantity, and then click in the work space of the applet window to drop it. When you're done choosing pieces, use the Move tool (the arrow) to drag them into the jars. You can always go back and get more pieces, or delete them with the Trash Can tool.

The jars in this applet are shown as stacked to make it easier to combine the jam and find out how much you have.

3.3: Making Granola

Consider the problem: To make 1 batch of granola, Kiran needs 26 ounces of oats. The only measuring tool he has is a 4-ounce scoop. How many scoops will it take to measure 26 ounces of oats?

Will the answer be more than 1 or less than 1?

Write a multiplication equation and a division equation that represent this situation. Use “?” to represent the unknown quantity.

Find the unknown quantity. If you get stuck, consider drawing a diagram.

The recipe calls for 14 ounces of mixed nuts. To get that amount, Kiran uses 4 bags of mixed nuts.
