Ela is knitting a scarf from a pattern. The pattern calls for \(4\frac{2}{12}\) yards of yarn. She has only \(2\frac{11}{12}\) yards of yarn. How much more yarn does Ela need to finish knitting the scarf? Explain how you found your answer.

Miguel’s class went to the state fair. The fairground is divided into sections. Rides are in \(\frac{6}{10}\) of the fairground. Games are in \(\frac{2}{10}\) of the fairground. Farm exhibits are in \(\frac{1}{10}\) of the fairground.

A. How much greater is the fraction of the fairground with rides than the fraction with farm exhibits? Draw a model to prove your answer is correct.

B. What fraction of the fairground has games and farm exhibits?
Write an equation to show your answer.

C. The rest of the fairground is refreshment booths. What fraction of the fairground is refreshment booths?  Describe the steps you follow to solve the problem.
