Question 29.

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.

\(\frac{□}{□}\)

Answer: \(\frac{5}{10}\).

Explanation:

As the fairground is divided into sections, rides are in \(\frac{6}{10}\) of the fairground, games are in \(\frac{2}{10}\) of the fairground and Farm exhibits are in \(\frac{1}{10}\) of the fairground. So the fraction of the fairground with rides than the fraction with farm exhibits is \(\frac{6}{10}\)– \(\frac{1}{10}\)

= \(\frac{5}{10}\) greater than farm exhibits.

Question 29.

B. What fraction of the fairground has games and farm exhibits?

Write an equation to show your answer.

Answer: \(\frac{3}{10}\).

Explanation:

The fraction of the fairground has games and farm exhibits is \(\frac{2}{10}\)+\(\frac{1}{10}\)

= \(\frac{3}{10}\).

Question 29.

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.

Answer: 9 \(\frac{1}{10}\).

Explanation:

As the fairground is divided into sections, rides are in \(\frac{6}{10}\) of the fairground, games are in \(\frac{2}{10}\) of the fairground and Farm exhibits are in \(\frac{1}{10}\) of the fairground. So the fraction of the fairground is refreshment booths \(\frac{6}{10}\)+\(\frac{2}{10}\)+\(\frac{1}{10}\)

= \(\frac{9}{10}\).

To find a fraction of the fairground is refreshment booths we will subtract \(\frac{9}{10}\) with 10, so

10- \(\frac{9}{10}\)

= \(\frac{100-9}{10}\)

= \(\frac{91}{10}\)

= 9 \(\frac{1}{10}\).
