Question

12.5:(-7/5)+1.5:(-7/5)

 

Answer 1

12,5 : (-7,5) + 1,5 : (-7,5)

= 12,5 . (-5/7) + 1,5 . (-5/7)

= (12,5 + 1,5) . (-5/7)

= 14 . (-5/7)

= -10 

Answer 2

12.5 :(-7/5)+1.5:(-7/5)

=(12.5+1.5):(-7/5)

=14:(-7/5)

=-10

Answer 3

=\(30:\frac{-7}{5}+5:\frac{-7}{5}\)

=\(\left(60+5\right):\frac{-7}{5}\)

=\(65\cdot\frac{5}{-7}\)

=\(\frac{-325}{7}\)

nhớ k cho mình nha

Answer 4

\(12,5:\left(-\frac{7}{5}\right)+1,5:\left(-\frac{7}{5}\right)\)

\(\Leftrightarrow\frac{12,5+1,5}{-\frac{7}{5}}=\frac{14}{-\frac{7}{5}}=-\frac{14}{\frac{7}{5}}=-\frac{14.5}{7}=-10\)
