Question

Sara has 7/21 yard of ribbon. What is the maximum number of 1/3 yard-long pieces Marilyn can cut from this ribbon?

Answer 1

Answer:

1

Step-by-step explanation:

Given parameters:

Length of ribbon  = $\frac{7}{21}$yards

Unknown:

Maximum number of $\frac{1}{3}$yards that can be cut = ?

Solution:

Maximum number of length that can be cut;

         = $\frac{Total length}{maximum number of length}$  

Maximum number of length = $\frac{\frac{7}{21} }{\frac{1}{3} }$  

Maximum number of length = $\frac{7}{21}$ x $\frac{3}{1}$   = 1

The maximum number of  $\frac{1}{3}$yards that can be cut is 1
