Example Questions

Example Question #1 : Use The Four Operations With Whole Numbers To Solve Problems

What equation is described below? 

\(\displaystyle 36\) is \(\displaystyle 6\) times as many as \(\displaystyle 6\)

Possible Answers:

\(\displaystyle 6\times6=36\)

\(\displaystyle 36\div6=6\)

\(\displaystyle 32\div6=6\)

\(\displaystyle 6+6=36\)

\(\displaystyle 6\times6=32\)

Correct answer:

\(\displaystyle 6\times6=36\)

Explanation:

\(\displaystyle 36\) is \(\displaystyle 6\) times as many as \(\displaystyle 6\)

In this phrase, "is" represents equal and "times" means multiplication. 

So we have \(\displaystyle 6\times6=36\)

\(\displaystyle 5\times11=55\)

\(\displaystyle 55\div11=5\)

\(\displaystyle 55\times11=5\)

\(\displaystyle 55\times5=11\)

Correct answer:

\(\displaystyle 5\times11=55\)

Explanation:

\(\displaystyle 55\) is \(\displaystyle 5\) times as many as \(\displaystyle 11\)

In this phrase, "is" represents equal and "times" means multiplication. 

So we have \(\displaystyle 5\times11=55\)

Example Question #2 : Common Core Math: Grade 4

What equation is described below? 

\(\displaystyle 60\) is \(\displaystyle 10\) times as many as \(\displaystyle 6\)

Possible Answers:

\(\displaystyle 60\div10=6\)

\(\displaystyle 6\times10=60\)

\(\displaystyle 60\times6=10\)

\(\displaystyle 60\div6=10\)

\(\displaystyle 5\times12=60\)

Correct answer:

\(\displaystyle 6\times10=60\)

Explanation:

\(\displaystyle 60\) is \(\displaystyle 10\) times as many as \(\displaystyle 6\)

In this phrase, "is" represents equal and "times" means multiplication. 

So we have \(\displaystyle 6\times10=60\)

Example Question #4 : Operations & Algebraic Thinking

What equation is described below? 

\(\displaystyle 36\) is \(\displaystyle 12\) times as many as \(\displaystyle 3\)

Possible Answers:

\(\displaystyle 36\3=12\)

\(\displaystyle 3\times12=36\)

\(\displaystyle 36\12=3\)

\(\displaystyle 12\div3=36\)

\(\displaystyle 3\times12=32\)

Correct answer:

\(\displaystyle 3\times12=36\)

Explanation:

\(\displaystyle 36\) is \(\displaystyle 12\) times as many as \(\displaystyle 3\)

In this phrase, "is" represents equal and "times" means multiplication. 

So we have \(\displaystyle 3\times12=36\)
