Scoops of Every Size
12 3/4 is 6/8, so 6 eighths. A scoop is 3 eighths. 6 ÷ 3 = 2 scoops.
210 5/6 is 10/12, so 10 twelfths. Ten cups of 1/12 fit.
3A 5/6 is 10/12, so ten twelfths are shaded. B shows only 5/12, and C is cut into sixths, not twelfths.
42 1 1/2 is 6/4. Each bow is 3/4. 6 ÷ 3 = 2 bows.
52 1/2 scoops 5/6 is 5 sixths and 1/3 is 2 sixths. 5 ÷ 2 = 2 1/2 scoops.
62/3 1/2 is 2/4, and a scoop is 3/4. 2 is two thirds of 3, so the rice fills 2/3 of a scoop.
71/2 The scoop holds 2 thirds, and the rice is 1 third. 1 is half of 2, so the rice fills 1/2 of a scoop.
81-C, 2-A, 3-D, 4-B Write both with the same bottom number, then count how many of the small piece fit.
9True 3/4 is 6/8 and a half is 4/8. One half fits, with 2/8 left over, which is half of another. 1 1/2 in all.
10False One half is two fourths, so two scoops of 1/4 fit: 1/2 ÷ 1/4 = 2.
113 2 1/4 is 9/4. Nine fourths in scoops of three fourths: 9 ÷ 3 = 3.
124 3 cups is 12 fourths. A scoop is 3 fourths. 12 ÷ 3 = 4 scoops.
