Reclassification of a Slope/Raster in QGIS 3
1. At first load your DEM Raster to Qgis canvas/screen,
2. If your Input DEM Raster is on 'Degree/WGS_1984' then,
Reproject your DEM Raster layer's EPSG from Geographic CRS 'Degree/WGS_1984' to
Projected CRS 'Transverse_Mercator/WGS_1984_UTM_Zone_..N'
#[Raster-Projections-Warp 'reproject']
3. Now, goto Raster-Analysis-Slope,
4. On processing toolbox, type reclass and select 'Reclassify by table',
5. If you want to vectorize that classified slope then go to Raster-conversion-Raster to Vector
