Question

Thelma drew this number line to show the number of eggs left in a carton.

The number line from 0 to 1 has 13 equally spaced tick marks. The first tick mark is 0 and the last tick mark is 1. A point on the fourth tick mark after 0 shows four over twelve.

Which fraction model is equal to Thelma’s fraction on her number line?


The rectangle is divided into 3 equal parts and one part is shaded.


The rectangle is divided into 6 equal parts and one part is shaded.


The rectangle is divided into 8 equal parts and one part is shaded.

Answer 1

There are 13 ticks so the interval 0 to 1 is split into 12 equal parts. The fourth tick after 0 is 4/12, which simplifies to 1/3. So the rectangle divided into 3 equal parts with one part shaded matches Thelma’s fraction.
