Answer key · Set B
One part of the whole
11/3 The circle has 3 equal parts and 1 is shaded, so the fraction is 1/3.
21/8 The square has 8 equal parts and 1 is shaded, so the fraction is 1/8.
3A One half is 1 part out of 2 equal parts. B has 3 parts and C has 6 parts.
4False One third needs 3 EQUAL parts. These parts are not the same size.
5True The circle has 6 equal parts and 1 is shaded: 1/6.
6B One eighth is 1 part out of 8 equal parts. A has 7 shaded and C has only 4 parts.
71/8 Each of the 8 equal parts is 1/8 long. The dot is at the end of the first part: 1/8.
81/6 The more equal parts a whole is cut into, the smaller each part. Cutting into 6 makes the smallest pieces.
93, 1, 2, 4 The more equal parts, the smaller each part. So 1/8 is smallest and 1/2 is biggest.
106 Each part is one sixth. It takes 6 sixths to make the whole bar.
111/4 Pip ate 1 of the 4 equal slices: 1/4.
