Answer 1

Mik chỉ làm đc câu c thui nha, sr
c.\(\text{ 3/59.(-14)/15+3/59.11/30-3/59.4/45=3/59 (-14/15+11/30-4/45) }\)

\(=3/59.(-59)/90=-1/30\)

Answer 2

c: \(\dfrac{3}{59}\cdot\dfrac{-14}{15}+\dfrac{3}{59}\cdot\dfrac{11}{30}-\dfrac{3}{59}\cdot\dfrac{4}{45}\)

\(=\dfrac{3}{59}\left(-\dfrac{14}{15}+\dfrac{11}{30}-\dfrac{4}{45}\right)\)

\(=-\dfrac{1}{30}\)
