Example Questions

Example Question #1419 : Numbers And Operations

Which of the equations is TRUE?

 

Possible Answers:

\(\displaystyle 7+8=20-5\)

\(\displaystyle 7+8=20-1\)

\(\displaystyle 7+8=20-3\)

\(\displaystyle 7+8=20-2\)

Correct answer:

\(\displaystyle 7+8=20-5\)

Explanation:

Both \(\displaystyle 7+8\) and \(\displaystyle 20-5\) equal \(\displaystyle 15\). So these two equations equal each other. \(\displaystyle 20-3=17\)\(\displaystyle 20-2=18\), and \(\displaystyle 20-1=19\). Because none of these equations equal \(\displaystyle 15\), they can’t be equal to \(\displaystyle 7+8\)

Example Question #352 : How To Add

Fill in the blank. 

\(\displaystyle 7+\)__________\(\displaystyle =11\)

Possible Answers:

\(\displaystyle 4\)

Correct answer:

\(\displaystyle 4\)

Explanation:

To find the missing piece of an addition problem, you can take the biggest number minus the smallest number. \(\displaystyle 11-7=4\), which means \(\displaystyle 7+4=11\).

Example Question #353 : How To Add

Fill in the blank. 

\(\displaystyle 8+\)__________\(\displaystyle =20\) 

Possible Answers:

\(\displaystyle 12\)

Correct answer:

\(\displaystyle 12\)

Explanation:

To find the missing piece of an addition problem, you can take the biggest number minus the smallest number. \(\displaystyle 20-8=12\), which means \(\displaystyle 8+12=20\).

Possible Answers:

\(\displaystyle 5\)

\(\displaystyle 1\)

\(\displaystyle 3\)

\(\displaystyle 4\)

\(\displaystyle 2\)

Correct answer:

\(\displaystyle 3\)

Explanation:

To find the missing piece of an addition problem, you can take the biggest number minus the smallest number. \(\displaystyle 12-9=3\), which means \(\displaystyle 9+3=12\).

Example Question #77 : Find The Missing Number In Addition And Subtraction Equations: Ccss.Math.Content.1.Oa.D.8

Fill in the blank. 

\(\displaystyle 5+\)__________\(\displaystyle =10\) 

Possible Answers:

\(\displaystyle 9\)

\(\displaystyle 7\)

\(\displaystyle 5\)

\(\displaystyle 8\)

\(\displaystyle 6\)

Correct answer:

\(\displaystyle 5\)

Explanation:

To find the missing piece of an addition problem, you can take the biggest number minus the smallest number. \(\displaystyle 10-5=5\), which means \(\displaystyle 5+5=10\).

Example Question #1422 : Numbers And Operations

Fill in the blank. 

\(\displaystyle 10+\)__________\(\displaystyle =14\) 

Possible Answers:

\(\displaystyle 3\)

\(\displaystyle 6\)

\(\displaystyle 4\)

\(\displaystyle 5\)

\(\displaystyle 2\)

Correct answer:

\(\displaystyle 4\)

Explanation:

To find the missing piece of an addition problem, you can take the biggest number minus the smallest number. \(\displaystyle 14-10=4\), which means \(\displaystyle 10+4=14\).

Example Question #79 : Find The Missing Number In Addition And Subtraction Equations: Ccss.Math.Content.1.Oa.D.8

Fill in the blank. 

\(\displaystyle 11+\)__________\(\displaystyle =16\) 

Possible Answers:

\(\displaystyle 7\)

\(\displaystyle 6\)

\(\displaystyle 9\)

\(\displaystyle 5\)

\(\displaystyle 8\)

Correct answer:

\(\displaystyle 5\)

Explanation:

To find the missing piece of an addition problem, you can take the biggest number minus the smallest number. \(\displaystyle 16-11=5\), which means \(\displaystyle 11+5=16\).

Example Question #1421 : Ssat Elementary Level Quantitative (Math)

Fill in the blank. 

\(\displaystyle 12+\)__________\(\displaystyle =18\)
