Answer 1

Answers:

a. 3 : 5 = 12 : 20

12 is four times 3, so multiply 5 by 4. (5 × 4 = 20)

b. 4 : 9 = 12 : 27

27 is three times 9, so multiply 4 by 3. (4 × 3 = 12)

c. 8 : 7 = 16 : 14

14 is two times 7, so divide 16 by 2. (16 ÷ 2 = 8)

d. 2 : 3 = 3 : 4 (?)

3 is one higher than 2, so add 1 to 3. (3 + 1 = 4)
