Example Question #231 : Number & Operations In Base Ten

Which statement is true?

 

Possible Answers:

\(\displaystyle 46< 59\)

\(\displaystyle 46>59\)

\(\displaystyle 46=59\)

Correct answer:

\(\displaystyle 46< 59\)

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. 

\(\displaystyle 4\) is less than \(\displaystyle 5\) which means that \(\displaystyle 46\) is less than \(\displaystyle 59\). Or \(\displaystyle 46< 59\) because the \(\displaystyle < \) sign means less than.
