Example Question #53 : Compare Two Digit Numbers: Ccss.Math.Content.1.Nbt.B.3

Which statement is true?

 

Possible Answers:

\(\displaystyle 50< 50\)

\(\displaystyle 50=50\)

\(\displaystyle 50>50\)

Explanation:

The \(\displaystyle =\) sign means equal. \(\displaystyle 50\) and \(\displaystyle 50\) are the same number which means they are equal. 

 

Example Question #54 : Compare Two Digit Numbers: Ccss.Math.Content.1.Nbt.B.3

Which statement is true?

 

Possible Answers:

\(\displaystyle 44< 45\)

\(\displaystyle 44>45\)

\(\displaystyle 44=45\)

Correct answer:

\(\displaystyle 44< 45\)

Explanation:

The \(\displaystyle < \) sign means less than. \(\displaystyle 44\) is less than \(\displaystyle 45\) because of the number in the ones place. \(\displaystyle 4\) has a lesser value than \(\displaystyle 5\), which means \(\displaystyle 44\) has a lesser value than \(\displaystyle 45\) 

Example Question #58 : Compare Two Digit Numbers: Ccss.Math.Content.1.Nbt.B.3

Which statement is true?

Possible Answers:

\(\displaystyle 56< 57\)

\(\displaystyle 56>57\)

\(\displaystyle 56=57\)

Correct answer:

\(\displaystyle 56< 57\)

Explanation:

The \(\displaystyle < \) sign means less than. \(\displaystyle 56\) is less than \(\displaystyle 57\) because of the number in the ones place. \(\displaystyle 6\) has a lesser value than \(\displaystyle 7\), which means \(\displaystyle 56\) has a lesser value than \(\displaystyle 57\)

The \(\displaystyle =\) sign means equal. \(\displaystyle 33\) and \(\displaystyle 33\) are the same number which means they are equal

Example Question #191 : Understanding Place Value

Which statement is true? 

 

Possible Answers:

\(\displaystyle 18< 23\)

\(\displaystyle 18>23\)

\(\displaystyle 18=23\)

Correct answer:

\(\displaystyle 18< 23\)

Explanation:

When you are comparing numbers with all different digits, you look at the greatest place value to determine which number is greater or less than. In this case, we are going to look at the tens place. 

\(\displaystyle 1\) is less than \(\displaystyle 2\) which means that \(\displaystyle 18\) is less than \(\displaystyle 23\). Or \(\displaystyle 18< 23\) because the \(\displaystyle < \) sign means less than.  

Example Question #62 : Compare Two Digit Numbers: Ccss.Math.Content.1.Nbt.B.3

Which statement is true? 

 

Possible Answers:

\(\displaystyle 17< 23\)

\(\displaystyle 17>23\)

\(\displaystyle 17=23\)

Correct answer:

\(\displaystyle 17< 23\)

Explanation:

When you are comparing numbers with all different digits, you look at the greatest place value to determine which number is greater or less than. In this case, we are going to look at the tens place. 

\(\displaystyle 1\) is less than \(\displaystyle 2\) which means that \(\displaystyle 17\) is less than \(\displaystyle 23\). Or \(\displaystyle 17< 23\) because the \(\displaystyle < \) sign means less than.

\(\displaystyle 20>36\)

\(\displaystyle 20< 36\)

Correct answer:

\(\displaystyle 20< 36\)

Explanation:

When you are comparing numbers with all different digits, you look at the greatest place value to determine which number is greater or less than. In this case, we are going to look at the tens place. 

\(\displaystyle 2\) is less than \(\displaystyle 3\) which means that \(\displaystyle 20\) is less than \(\displaystyle 36\). Or \(\displaystyle 20< 36\) because the \(\displaystyle < \) sign means less than.
