8.2: How Much in One Batch?

To make 5 batches of cookies, 10 cups of flour are required. How many cups of flour does each batch require?

We can write equations and draw a diagram to represent this situation. They help us see that each batch requires 2 cups of flour.
5⋅?=10
10÷5=?

For each question, write a multiplication equation and a division equation, draw a diagram, and answer the question.

To make 4 batches of cupcakes, it takes 6 cups of flour. How many cups of flour are needed for 1 batch?

Challenge Question!
  • Start with a tape diagram of length 1 unit. This is step 1.
  • Color in the middle third of the tape diagram. This is step 2.
  • Do the same to each remaining segment that is not colored in. This is step 3.
  • Keep repeating this process.
How much of the diagram is colored in after step 2? Step 3? Step 10?

1

If you continue this process, how much of the tape diagram will you color?

1

Can you construct a process that will give you a similar kind of object? For example, color the first fifth instead of the middle third of each strip.
