Kwiibheji ezilinganayo zemali elinganayoibhejiIbheji yemali elinganayoObomvu/omnyama, angalinganiyo/alinganayo, aphezulu/aphantsi. Amanani ali-18, ihlawula u-1:1.Funda yonke → ilandela ifomula yokuwa komngcakazi; iibheji ezinkulu, nangona kumangalisa, ziphucula amathuba okufikelela kwinjongo kuba zibeka imali encinci phambi kwenzuzo yekhasino.
