Answer 1

\(\dfrac{5}{6}=\dfrac{5}{6};6=2\cdot3\)

\(\dfrac{21}{60}=\dfrac{7}{20};20=2^2\cdot5\)

\(-\dfrac{8}{125}=-\dfrac{8}{125};125=5^3\)

\(\dfrac{5}{44}=\dfrac{5}{44};44=2^2\cdot11\)

\(\dfrac{28}{-63}=-\dfrac{28}{63}=-\dfrac{4}{9};9=3^2\)

\(\dfrac{37}{800}=\dfrac{37}{800};800=2^5\cdot5^2\)

\(\dfrac{12}{75}=\dfrac{4}{25};25=5^2\)

\(-\dfrac{7}{8}=-\dfrac{7}{8};8=2^3\)
