Vocabulary Report

  • Proportion -

    An equation stating the two ratios are equal. A comparison of two quantities.

  • Rate -

    A comparison of the measurements of two different units or objects. A rate can be thought of as direct comparison of two sets or as an average amount.

  • Ratio -

    A ratio is a comparison of two quantities that tells the scale between them. Ratios may be expressed as quotients, fractions, decimals, percents, or given in the forms a:b or a to b..

  • Unit Rate -

    A unit rate compares an amount o a single unit. Unit rates are often found by scaling other rates.

  • Scale (Scaling) -

    The scale is the number a ratio is multiplied by to find an equivalent ratio. Scaling a ratio produces any number of equivalent ratios, which all have the same units and the same average distribution.
