The (W,Q2) dependence of the ratio of inclusive electron scattering cross sections for 15N /12C was determined in the kinematic ranges 0.8 < W < 2 GeV and 0.2 < Q2 < 1 GeV2 using 2.285 GeV electrons and the CLAS detector at Jefferson Lab. The ratios exhibit only slight resonance structure, in agreement with a simple phenomenological model and an extrapolation of deep-inelastic scattering ratios to low Q2. Ratios of 4He /12C using 1.6 to 2.5 GeV electrons were measured with very high statistical precision and were used to correct for He in the N and C targets. The (W,Q2) dependence of the 4He /12C ratios is in good agreement with that of the phenomenological model and exhibit significant resonance structure centered at W=0.94,1.23, and 1.5 GeV.
