8/9 ... 24/27             20/19 ... 20/27        8/7 ... 9/8        1 ...15/14

Answer 1

9/14 .<.. 11/14           4/25 .<.. 4/23          5/6 ..<. 7/8         1 ..>. 14/15

8/9 ..=. 24/27             20/19 ..>. 20/27        8/7 .>.. 9/8        1 .<..15/14

Answer 2

\(\dfrac{9}{14}< \dfrac{11}{14};\dfrac{8}{9}=\dfrac{24}{27}\)

\(\dfrac{4}{25}< \dfrac{4}{23};\dfrac{20}{19}>\dfrac{20}{27}\)

\(\dfrac{5}{6}< \dfrac{7}{8};\dfrac{8}{7}>\dfrac{9}{8}\)

\(1>\dfrac{14}{15};1< \dfrac{15}{14}\)

Answer 3

9/14 .<.. 11/14           4/25 .<.. 4/23          5/6 ..<. 7/8         1 ..>. 14/15

8/9 ..=. 24/27             20/19 ..>. 20/27        8/7 .>.. 9/8        1 .<..15/14

Answer 4

9/14 < 1/14   4/25 < 4/23   5/6 < 7/8    1 < 14/15

8/9 = 24/27   20/19 > 20/27     8/7 > 9/8   1 < 15/14

Answer 5

9/14 .<.. 11/14           4/25 .<.. 4/23          5/6 ..<. 7/8         1 ..>. 14/15

8/9 ..=. 24/27             20/19 ..>. 20/27        8/7 .>.. 9/8        1 .<..15/14

Answer 6

\(\dfrac{9}{14}< \dfrac{11}{14}\)       \(\dfrac{4}{25}< \dfrac{4}{23}\)   \(\dfrac{5}{6}< \dfrac{7}{8}\)      \(1>\dfrac{14}{15}\)       \(\dfrac{8}{9}=\dfrac{24}{27}\)     \(\dfrac{20}{19}>\dfrac{20}{27}\)      \(\dfrac{8}{7}>\dfrac{9}{8}\)     1<\(\dfrac{15}{14}\)
