Example Question #254 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

\(\displaystyle \frac{\begin{array}[b]{r}1\\ \times 3\end{array}}{ \ \ \ \space}\)

 

 

Possible Answers:

\(\displaystyle 3\)

\(\displaystyle 2\)

\(\displaystyle 1\)

\(\displaystyle 4\)

\(\displaystyle 5\)

Correct answer:

\(\displaystyle 3\)

Explanation:

Multiplication can be thought of as repeated addition, or as objects in a group. 

\(\displaystyle 1\times3\) means adding \(\displaystyle 3\) one time. 

\(\displaystyle 3=3\) and \(\displaystyle 1\times3=3\)

Or we can think of this as grouping objects. We have \(\displaystyle 1\) group, with \(\displaystyle 3\) objects in each group. We can count up the total number of objects, in this case triangles.
