Answer 2

=55/16

Answer 3

(1,5 - 25% ). \(2\dfrac{3}{4}\)

=(1,5 - \(\dfrac{25}{100}\)) . \(\dfrac{11}{4}\)

=> \(\left(1,5-0,25\right).2,75\)

=> \(1,25.2,75\)

=3,4375

Answer 4

= (1,5 - 0,4) . \(\dfrac{11}{4}\)

= 1,1 . \(\dfrac{11}{4}\)

= \(\dfrac{11}{10}\).\(\dfrac{11}{4}\)

=\(\dfrac{121}{40}\)
