Відповідь:

а) 4 ÷ 1/5 = 4 ÷ (1/5) = 4 * 5 = 20

b) 6 ÷ 1/2 = 6 ÷ (1/2) = 6 * 2 = 12

c) 5 ÷ 1/4 = 5 ÷ (1/4) = 5 * 4 = 20

d) 10 ÷ 5/7 = 10 ÷ (5/7) = 10 * (7/5) = 14

e) 14 ÷ 7/8 = 14 ÷ (7/8) = 14 * (8/7) = 16

f) 25 ÷ 5/6 = 25 ÷ (5/6) = 25 * (6/5) = 30

g) 4/5 ÷ 8 = (4/5) ÷ 8 = (4/5) * (1/8) = 1/10

h) 9/10 ÷ 27 = (9/10) ÷ 27 = (9/10) * (1/27) = 3/90 = 1/30

i) 7/9 ÷ 14 = (7/9) ÷ 14 = (7/9) * (1/14) ≈ 0.042

j) 12/13 ÷ 6 = (12/13) ÷ 6 ≈ 0.184

k) 15/16 ÷ 10 = (15/16) ÷ 10 = (15/16) * (1/10) = 3/32
