Page "Dark matter" Paragraph 7

According to observations of structures larger than solar systems, as well as Big Bang cosmology interpreted under the Friedmann equations and the FLRW metric, dark matter accounts for 23 % of the mass-energy content of the observable universe.

In comparison, ordinary matter accounts for only 4. 6 % of the mass-energy content of the observable universe, with the remainder being attributable to dark energy.

From these figures, dark matter constitutes 83 %, ( 23 /( 23 + 4. 6 )), of the matter in the universe, whereas ordinary matter makes up only 17 %.
