Using data collected in the DELPHI detector at LEP-1, measurements of the inclusive tau branching ratios for decay modes containing one, three, or five charged particles have been performed, giving the following results: [begin{array}{llcr} B_1 & equiv B(tau^- to(particle)^- ≥ 0π^0 ≥ 0K^0ν_tau(bar{ν})) & = & (85.316±0.093±0.049)%; B_3 & equiv B(tau^- to 2h^-h^+ ≥ 0π^0 ≥ 0K^0ν_tau) & = & (14.569±0.093±0.048)%; B_5 & equiv B(tau^- to 3h^-2h^+ ≥ 0π^0 ≥ 0K^0ν_tau) & = & (0.115±0.013±0.006)%, ] where h is either a charged π or K meson. The first quoted uncertainties are statistical and the second systematic.
