2/9 × 18 = (2×18)/9 = 36/9 = 4 Alternatively, cancelling as you go: 2/9 × 18 = (2×18)/9 = 2×(18/9) = 2×2 = 4
20, is the sum of 18 and 2.
18 ÷ 9 x 2 = (18 ÷ 9) x 2 = 2 x 2 = 4
The total number of shared electrons in a molecule of CH2O (formal charge -2) is 18. Each hydrogen atom shares 1 electron, each carbon atom shares 4 electrons, and the oxygen atom shares 6 electrons, adding up to a total of 18 shared electrons.

16 divided by 2 equals 8. Each equal share would be 8.
2/9 × 18 = (2×18)/9 = 36/9 = 4 Alternatively, cancelling as you go: 2/9 × 18 = (2×18)/9 = 2×(18/9) = 2×2 = 4
In a carbon-carbon double bond, and in any other non-dative covalent double bond, four electrons are shared in total. Two are shared from each atom. In single bonds, one electron from each atom is shared, and three from each are shared in triple bonds.
