Question

1,75 x (7\(\dfrac{16}{21}\))-(4\(\dfrac{1}{3}\)+2,25) : \(\dfrac{158}{60}\)

Answer 1

=1,75.(−1621)−(133+2,25):15860

=−4,3−7912:7930

=−43−52

Answer 2

à mk nhầm, cái này mới đúng:

=$1,75.\left(-\frac{16}{21}\right)-\left(\frac{13}{3}+2,25\right):\frac{158}{60}$

$=-4,3-\frac{79}{12}:\frac{79}{30}$

$=-\frac{4}{3}-\frac{5}{2}$

$=-\frac{23}{6}$
