Whole numbers x Fractions

Alexander needs 2/3 cup of sugar to make a batch of cookies. He wants to make 4 batches of cookies. How many cups of sugar does he need for all the batches of cookies?

• $\frac{6}{3}$

  
  

• $\frac{8}{3}$

• $\frac{8}{12}$

• $\frac{2}{12}$

 $3\ \times\ \frac{2}{4}\ =\ ?$  

The product of the problem above will be between which 2 numbers?

•  $\frac{6}{12}$  

•  $\frac{6}{4}$  

•  $\frac{2}{4}$ 

•  $\frac{2}{12}$  

 $6\ \times\ \frac{4}{5}$  

CHOOSE TWO!

•  $24\ \times\ \frac{1}{5}$  

•  $10\ \times\ \frac{1}{5}$  

•  $\frac{24}{5}$  

•  $\frac{24}{30}$  

 $4\ \times\ \frac{2}{3}$  

How can the expression above be rewritten as repeated addition?

•  $4\ +\ \frac{2}{3}$  

•  $\frac{2}{3}+\frac{2}{3}+\frac{2}{3}+\frac{2}{3}$  

• 4 + 4 + 4 + 4

•  $\frac{2}{3}+\frac{2}{3}+\frac{2}{3}$
