Benchmark Fractions

Benchmark fractions are common fractions like 1/2, 1/4 and 1/5 -- knowing the decimals and percents associated with these benchmarks can help students understand different representations of numbers while creating fluency and confidence.  1/2, 1/4 and 1/5 are terminating decimals that end (0.5, 0.25 and 0.2). Repeating decimals, such as 1/3 = .33333repeating, should be written as .3 with a line above the 3.
