Question

8. Simplily (1) (21.6 -1.2) x 3.9 (11) (2.8 x 1.6) + 12.8 (iii) (12.8 + 0.125) = 3.2​

Ayla · Answer

Answer:   (i) (21.6 -1.2) x 3.9  = 20.4 × 3.9  = 79.56    (ii) (2.8 x 1.6) + 12.8  = 4.48 + 12.8  = 17.28    (iii) (12.8 + 0.125) = 3.2  = 12.925 - 3.2 (I think that it will be '-', as '-' is a bit similar to '=')  = 9.785    Hope these helps :)
