Example Questions

Example Question #1151 : Common Core Math: Grade 5

Linda made \(\displaystyle 9\) gallons of punch. \(\displaystyle \frac{1}{10}\) of the punch was water. How much water did she use to make the punch? 

 

Possible Answers:

\(\displaystyle \frac{10}{10}\)

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

\(\displaystyle 10\)

\(\displaystyle 9\)

\(\displaystyle \frac{1}{10}\)

Correct answer:

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

Explanation:

A keyword in our question that gives us a clue that we are going to multiply to solve this problem is the word "of". \(\displaystyle \frac{1}{10}\) of the punch is water. 

We know that we have \(\displaystyle 9\) gallons of punch so we can set up our multiplication problem.

\(\displaystyle \frac{1}{10}\times9\) 

 9 10

 \(\displaystyle \frac{1}{10}\times9\) which means \(\displaystyle \frac{1}{10}\) of each group of \(\displaystyle 9=\frac{9}{10}\)

Example Question #2981 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

Malinda lives \(\displaystyle \frac{8}{9}\) of a mile away from her friend's house. She walked \(\displaystyle \frac{1}{3}\) of the way there and then stopped to get ice cream from an ice cream truck driving by. How far did she travel before she stopped to get ice cream? 

Possible Answers:

\(\displaystyle 9\textup { miles}\)

\(\displaystyle \frac{9}{27}\textup { of a mile}\)

\(\displaystyle \frac{7}{27}\textup { of a mile}\)

\(\displaystyle 7\textup { miles}\)

\(\displaystyle \frac{8}{27}\textup { of a mile}\)

Correct answer:

\(\displaystyle \frac{8}{27}\textup { of a mile}\)

Explanation:

A keyword in our question that gives us a clue that we are going to multiply to solve this problem is the word "of". \(\displaystyle \frac{1}{3}\) of the way to her friends house she stopped. 

We know that her friend lives \(\displaystyle \frac{8}{9}\) of a mile away from her so we can set up our multiplication problem. 

\(\displaystyle \frac{1}{3}\times\frac{8}{9}\)

We can set up a tiled area model to help us solve the problem.

We use the denominators for the dimensions of our area model, and we use the numerators to fill parts of the area model.

8 27

We make the area model \(\displaystyle 9\) by \(\displaystyle 3\) because those are the denominators of our fractions. We shade up \(\displaystyle 1\) and over \(\displaystyle 8\), because those are the numerators of our fractions. Our answer is a fraction made up of the boxes that are shaded (the numerator) and the total tiles in the area model (the denominator).  

\(\displaystyle \frac{1}{3}\times\frac{8}{9}=\frac{8}{27}\)
