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​

Answer 1

Answer:

1- 79.56

2:- 17.28

Step-by-step explanation:

1:- (21.6-1.2)*3.9

=20.4*3.9

79.56

2:- (2.8*1.6)+12.8

= 4.48+12.8

=17.28

Answer 2

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 :)
