Question

Kim has fraction 1 over 2 cup of almonds. She uses fraction 1 over 8 cup of almonds to make a batch of pancakes. Part A: How many batches of pancakes can Kim make with fraction 1 over 2 cup of almonds? (4 points) Part B: On your own paper, draw a fraction model that shows the total number of batches of pancakes that Kim can make with fraction 1 over 2 cup of almonds. Make sure to label the model. Below, explain your model in detail to describe how this model visually shows the solution for Part A.

Answer 1

The answer to Part A is 4 batches. Divide 1/2 by 1/8:)

Answer 2

Answer:

Part A :

Original part of the almond = $\frac{1}{2}$

The part of almond in each batch of pancake = $\frac{1}{8}$

Hence, the total number of batches of pancakes

$=\frac{\text{Original part of almond}}{\text{Part of almond in each pancake}}$

$=\frac{1/2}{1/8}$

$=\frac{8}{2}$

= 4

Part B :

In the below diagram,

∵ $\frac{1}{2}= \frac{1\times 4}{2\times 4}=\frac{4}{8}$

$\frac{1}{2}\div \frac{1}{8}=\frac{4}{8}\div \frac{1}{8} = \frac{4}{1}=4$
