f ) 0,75 - \(\left(2\dfrac{1}{3}+0,75\right)\)+ 32 . \(\left(-\dfrac{1}{9}\right)\)
= 0,75 - \(\left(\dfrac{7}{3}+\dfrac{3}{4}\right)\)+ 9 . \(\left(-\dfrac{1}{9}\right)\)
= 0,75 - \(\left(\dfrac{28}{12}+\dfrac{9}{12}\right)\)+ 9 . \(\left(-\dfrac{1}{9}\right)\)
= 0,75 - \(\dfrac{37}{12}\) + 9 . \(\left(-\dfrac{1}{9}\right)\)
= 0,75 - \(\dfrac{37}{12}\) + ( - 1 )
= \(\dfrac{3}{4}\) - \(\dfrac{37}{12}\) + ( - 1 )
= \(\dfrac{9}{12}\) - \(\dfrac{37}{12}\) + ( - 1 )
= \(-\dfrac{28}{12}\) + ( - 1 )
= \(-\dfrac{28}{12}\) + \(\left(-\dfrac{12}{12}\right)\)
= \(-\dfrac{10}{3}\)
=3/4-7/3-3/4+9*(-1/9)
=-7/3-1
=-10/3
