Question

e, \(\dfrac{3}{11}\).(2\(\dfrac{2}{3}\)-1,75)

f,( \(\dfrac{3}{4}\) + 0,5 ) : ( \(\dfrac{4}{5}\)-0,6)

Answer 1

=\(\dfrac{3}{11}.\left(\dfrac{4}{3}-\dfrac{7}{4}\right)\)

=\(\dfrac{3}{11}.\left(\dfrac{16}{12}-\dfrac{21}{12}\right)\)

=\(\dfrac{3}{11}.\left(-\dfrac{5}{12}\right)\)

=\(-\dfrac{15}{132}\)

=\(-\dfrac{5}{44}\)

Answer 2

f)=\(\left(\dfrac{3}{4}+\dfrac{1}{2}\right):\left(\dfrac{4}{5}-\dfrac{3}{5}\right)\)

=\(\left(\dfrac{6}{8}+\dfrac{4}{8}\right):\left(\dfrac{4}{5}-\dfrac{3}{5}\right)\)

=\(\dfrac{5}{4}:\dfrac{1}{5}\)

=\(\dfrac{25}{4}\)
