What is a benchmark fraction?

In math, benchmark fractions can be defined as common fractions that we can measure or judge against, when measuring, comparing, or ordering other fractions.

Benchmark fractions are easy to visualize and identify, and thus, help in estimating the parts. When comparing two fractions with different numerators and denominators, we can either make their denominators common or compare them to a benchmark fraction such as 1/2.

Benchmark fractions are most helpful when fractions to be compared are placed on a number line against the benchmarks.

 Hi All, Here is an introduction to the Unit. Stretching and Shrinking Overview of Ideas SIMILARITY Two figures are similar if: (1) the measures of their corresponding angles are equal and (2) the lengths of their corresponding sides increase by the same factor, called the scale factor . SCALE FACTOR The number used to multiply the lengths of a figure to stretch or shrink it into a similar image. A scale factor larger than 1 will enlarge a figure. A scale factor between 0 and 1 will reduce a figure. Preview activity: You will need: A ruler A pencil A blank sheet of paper 1. Draw a rectangle on the paper with whole number side lengths between 1-4 inches 2. Label its corners ABCD 3. Draw a second rectangle similar to the first (ABCD) with a scale factor of ½.  (reduce each side length by ½.   4. Label its corners EFGH. 5. Draw a right triangle with whole number leg lengths between 1-4 inches 6. Label its corners ABC 7. Draw a second right triangle similar to the first (ABC) with a scal
