Example: "The map shows a representative fraction of 1:50,000, indicating that one unit on the map corresponds to 50,000 units in reality."
Alternatives: "a proportional part of" or "a typical fraction of".

The second panel shows a representative fraction of the thermal melt curves that showed positive shifts for the tested proteins.
A representative fraction of the VHH library was cultured and infected with VCSM13 helper phages to express the VHH at the tip of phage particles [18].
It is conceivable that a representative fraction of the population could be convinced to share health-related data with public health authorities, either directly or through third parties such as health cooperatives.

Although understandably not at the quality of a model organism, this transcriptome appears to be a large representative fraction of transcribed loci in Quercus and is the most complete for this genus reported to date.
The annotation of a large and representative fraction of the database makes FishNet a valuable resource not only for zebrafish researchers but also to those in other disciplines who wish to further examine results in fish or undertake comparative analyses.
If proven successful, such initiatives may also improve the validity of our future informatics-based periodontitis surveillance efforts, because a higher and presumably more representative fraction of the target population will have recent periodontal disease assessment data available.
A key monitoring well utility is their proportionately greater sample draw from permeable horizons constituting a significant contaminant flux pathway and hence representative fraction of source mass flux.
Representative fractions of cell surface proteins were prepared by briefly treating cells with 1 mg/ml sulfo-NHS-SS-biotin (Pierce, Rockford, IL, USA) for 10 min at 37°C to biotinylate integral surface membrane proteins with extracellular primary amines, which were subsequently purified using streptavidin Sepharose (GE Healthcare, Waukesha, WI, USA).
