Answer 1

a: -7/15=-28/60

5/12=25/60

b: 1/5=6/30

-2/3=-20/30

7/10=21/30

Answer 2

\(-\dfrac{7}{15}=\dfrac{-7.4}{15.4}=\dfrac{-28}{60};\dfrac{5}{12}=\dfrac{5.5}{12.5}=\dfrac{25}{60}\)

\(\dfrac{1}{5}=\dfrac{1.6}{5.6}=\dfrac{6}{30};\dfrac{-2}{3}=\dfrac{-2.10}{3.10}=\dfrac{-20}{30};\dfrac{7}{10}=\dfrac{7.3}{10.3}=\dfrac{21}{30}\)
