•  $4\times\frac{2}{4}$  will be greater than  $4\times\frac{1}{1}$  because  $\frac{2}{4}$  is greater than  $\frac{1}{1}$  

•  $4\times\frac{2}{4}$  will be less than  $4\times\frac{1}{1}$  because  $\frac{2}{4}$  is greater than  $\frac{1}{1}$  

•  $4\times\frac{2}{4}$  will be greater than  $4\times\frac{1}{1}$  because  $\frac{2}{4}$  is less than  $\frac{1}{1}$  

•  $4\times\frac{2}{4}$  will be less than  $4\times\frac{1}{1}$  because  $\frac{2}{4}$  is less than  $\frac{1}{1}$  

What is the value of  $7\ \times\ \frac{1}{4}$  , and why?

• The value is  $\frac{1}{28}$  because  $\frac{1}{7}\times\frac{1}{4}=\frac{1}{28}$  

• The value is  $\frac{4}{7}$  because  $\frac{1}{7}\times\frac{4}{1}=\frac{4}{7}$  

• The value is  $\frac{7}{4}$  because  $\frac{7}{1}\times\frac{1}{4}=\frac{7}{4}$  

• The value is  $\frac{28}{1}$  because  $\frac{7}{1}\times\frac{4}{1}=\frac{28}{1}$
