If the weight of 1 liter of water is 1 kilogram, then the volume of 0.1 gram of water is how many cubic millimeters.

(880 ÷ 11 + 170) X ? = 40% of 1000 

(1/3) + (2/5) + (3/4) + (11/10) = 3 – (?/12)

(15 × 225) ÷ (45 × 5) + 480 = ? + 25% of 1240

(21 × 51 + 81)/(9 × 14 - 30) = ?

32² – 18² + 11 × 24 = ?
