On a number line, which point is **exactly halfway** between 0 and 1?  \n\nA.\u202f\u202f\u00bc\u2003\u2003B.\u202f\u202f\u2153\u2003\u2003C.\u202f\u202f\u00bd\u2003\u2003D.\u202f\u202f\u00be  \n\n---\n\n## Answer Key (with one\u2011sentence explanations)\n\n1. **B** \u2013 1\u20445 is a unit fraction because the numerator is 1.  \n2. **B** \u2013 The second tick after 0 marks \u00bd on the line.  \n3. **D** \u2013 4\u20445 is the largest because the same denominator (5) makes the biggest numerator the biggest fraction.  \n4. **A** \u2013 5\u20443 is greatest; with the same numerator, the smaller denominator gives a larger value.  \n5. **C** \u2013 The third tick after 0 represents \u00be.  \n6. **B** \u2013 The picture that shows the bar divided into three equal parts with one part shaded is 1\u20443.  \n7. **A** \u2013 2\u20444 simplifies to 1\u20442, so they are the same size.  \n8. **A** \u2013 1\u20443 is smaller than 2\u20443 because it represents fewer parts of the whole.  \n9. **A** \u2013 3\u20448 is closest to 0; it is the smallest numerator/denominator pair listed.  \n10. **C** \u2013 \u00bd is exactly halfway between 0 and 1 on a number line.
