Answer 1

Answer:

Step-by-step explanation:

q4 i) 2.3 - [ 1.89 - {3.6 - (2.7 - 0.8 - 0.03)}]

     =  2.3 - [ 1.89 - {3.6 - (2.7 - 0.77)}]

     =  2.3 - [ 1.89 - {3.6 - 1.93}]

      = 2.3 - [ 1.89 - 1.67]

      = 2.3 - 0.22

      = 2.08

ii) 4.5 - 1/2 of (7.6 - 3.5)+ 2.3 x 4.05

  = 4.5 - 1/2 x 4.1 + 9.315

   = 4.5 - 2.05+9.315

   = 13.815 - 2.05

  = 11.765
