The branching ratios of D0 → K0K0 and D0 → Ks0Ks0Ks0 relative to D0 → K0π+π- are reported. The data were accumulated in the 1990-1991 fixed target running period of the Fermilab high energy photoproduction experiment E687. Γ (D0 → K0K0)/Γ (D0 → K0π+π- is measured to be 0.039±0.013±0.013 and Γ (D0→Ks0Ks0Ks0)/Γ (D0 → K0π+π-) is measured to be 0.035±0.012±0.006. We also measure Γ (D0 → K0π+π-/Γ (D0 → K-π+) to be 1.61±0.10±0.15.
