55/1000.5555%

325/1003.25325%

Answer 2:

(a):{(6 + 7) x 4} - (2 x 8) = 36

Proof:

{(13) x 4} - (16) = 36

52-16 = 36

36 = 36

(c):6 + [7 x {(4 - 2) x 8}] = 118

Proof:

6 + [7 x 16] = 118

6 + 112 = 118

118 = 118

(b):(6 + 7) x (4 - 2) x 8 = 208

Proof:

13 x 2 x 8 = 208

208 = 208

Answer 3:

(a): 70 + 8.57 + 0.057 = 78.627

Rounding off

= 78.63

= 78.6

= 79

(b):800.05 - 62.875 = 737.175

Rounding off

= 737.18

= 737.2

= 737

Answer 4:

(a):(9/4) - (5/18) / (4/9) =

(9/4) - [(5/18) / (4/9)]

(9/4) ...
