Question

-3 phần 16 ; 5 phan 24 ; -21 phần 56

Answer 1

quy đồng ạ

Answer 2

\(\dfrac{-3}{16};\dfrac{5}{24};\dfrac{-21}{56}\) MSC : 336

\(\dfrac{-3}{16}=\dfrac{\left(-3\cdot21\right)}{16\cdot21}=\dfrac{-63}{336}\)

\(\dfrac{5}{24}=\dfrac{5\cdot14}{24\cdot14}=\dfrac{70}{336}\)

\(\dfrac{-21}{56}=\dfrac{\left(-21\cdot6\right)}{56\cdot6}=\dfrac{-126}{336}\)

Answer 3

\(-\dfrac{3}{16}=\dfrac{-3.12}{16.21}=-\dfrac{63}{336}\)

\(\dfrac{5}{24}=\dfrac{14.5}{14.24}=\dfrac{70}{336}\)

\(-\dfrac{21}{56}=\dfrac{-21.6}{56.6}=-\dfrac{126}{336}\)

Answer 4

=63/336

=70/336

=-126/336
