Zac is making cookies, but he does not have enough brown sugar to make a full recipe. The full recipe calls for

If Zac has enough brown sugar for

Represent the

cup of brown sugar the recipe calls for with a diagram. First draw a rectangle to represent a full cup of brown sugar. Now try to solve the problem with this information.

Represent the portion of brown sugar that Zac has if he makes only

of the recipe.

How can you subdivide your shaded diagram from part (a) into fifths (5 equal parts)?

Which part of the sugar is 3 of the fifths?

One way this can be represented is...

Label the portion of brown sugar Zac needs.

What mathematical operation should Zac use to find the amount of brown sugar he has? Write an expression and then calculate its value.
