Shoes

Jim and Dora are collecting shoes for a yard sale. Dora collected 1/2 as many shoes as Jim did. Jim collected 3/7 of a bag of shoes. How many bags of shoes did Dora collect?

Correct answer:

d =  3/14

Step-by-step explanation:

$$\begin{gathered} j=\frac{3}{7}\doteq 0.4286 \\ d=\frac{1}{2}\cdot j=\frac{1}{2}\cdot \frac{3}{7}=\frac{1\cdot 3}{2\cdot 7}=\frac{3}{14}=0.2143 \end{gathered}$$
