Magnitude Comparison With Fractions
) tested whether difficulties with decimals and fractions stem from the fact that adults do not treat values presented in these formats as being part of the same number system as whole numbers. On each trial, participants were shown two numbers presented as decimals, fractions, and/or whole numbers and asked to indicate which number is larger as quickly and accurately as possible.
Responses were faster and more accurate when the ratio between the two numbers was larger, regardless of whether the two numbers being compared were presented in the same notation (e.g., 1/2 vs. 1/4) or different notations (e.g., 1/2 vs. .25). The fact that such ratio effects were observed for all comparisons suggests that participants represent fractions, decimals, and whole numbers as falling along the same mental continuum
