Answer key · Set B
Pieces of the same size
1A 1 fourth and 2 fourths make 3 fourths. Bar A has 3 of 4 equal parts shaded. Bar C has eighths.
25/8 The pieces are all eighths. 2 eighths and 3 eighths make 5 eighths. The bottom stays 8.
37/9 Add the tops and keep the bottom: 3 + 4 = 7, so the answer is 7/9.
4False Do not add the bottoms. The pieces are sixths and stay sixths, so 2/6 + 3/6 = 5/6.
55/12 8 twelfths take away 3 twelfths leaves 5 twelfths. The bottom stays 12.
6True Take the tops away and keep the bottom: 5 − 2 = 3, so the answer is 3/9.
71/3 2 thirds is 1 third and 1 third more.
84/6 The whole pie is 6/6. 6/6 − 2/6 = 4/6. Do not change the bottom.
97/7 4 sevenths and 3 sevenths make 7 sevenths, and 7 sevenths is one whole.
107/10 2 tenths and 5 tenths make 7 tenths. The path is cut into tenths.

122, 1, 3, 4 3/12 + 1/12 = 4/12 and 2/12 + 5/12 = 7/12. In order: 4/12, 5/12, 7/12, 8/12.
