Marcus plants daffodils in  $\frac{6}{10}$  of his garden and sunflowers in  $\frac{11}{100}$  of his garden.  Write an addition equation to show how to find the total fraction of the garden in which Marcus plants daffodils and sunflowers. 
Choose all that apply. 

•  $\frac{6}{10}+\frac{11}{100}=\frac{71}{100}$  

•  $\frac{6}{10}+\frac{11}{10}=\frac{17}{10}$  

•  $\frac{6}{10}+\frac{11}{100}=\frac{17}{110}$  

•  $\frac{60}{100}+\frac{11}{100}=\frac{71}{100}$

Part A
Aiden paints  $\frac{4}{10}$  of a fence.  Drew paints  $\frac{4}{100}$  of the same fence. 

• Drew is correct because  $\frac{4}{10}$  is less than  $\frac{4}{100}$  because the denominator 10 is less than the denominator 100.

• Drew is correct because  $\frac{4}{100}$  is equivalent to  $\frac{40}{10}$  and  $\frac{40}{10}$  is more than  $\frac{4}{10}$  .

• Drew is not correct because  $\frac{4}{10}$  is equivalent to  $\frac{4}{100}$ , so Drew and Aiden paint the same amount.  

• Drew is not correct because  $\frac{4}{10}$  is equivalent to  $\frac{40}{100}$  and  $\frac{40}{100}$  is more than  $\frac{4}{100}$
