Introduction
Comparing Fractions
The activity aims at assisting students to develop flexibility with a number of
strategies. It sets expectations for various procedures of ordering fractions. Although
determining a common denominator of comparing fractions is a good strategy, it is inefficient
for numerous pairs of fractions (Ebby, Sirinides, Supovitz, & Oettinger, 2013). For instance,
in relation to the assignment provided, descriptions below show a way of comparing fractions
by an analysis of their size. The learner may share extra strategies. The first one involves
comparing to one-half. One-half is less than five-eighths, and one-half is greater than two-
fifths; thus, one-half is smaller. The second one revolves around common numerators; fifths
are smaller than fourths, so three-fifths is less than three-fourths. The third one entails
comparing to one. Both the provided fractions are one fraction less than one. One-sixth is
greater than one-eighth, so seven eighths lack a lesser part and is closer to 1. The fourth
activity is comparing same numerators. Two-sixths is equal to one-third (Ebby et al., 2013).
Sixths are lesser than fifths, and, as such, two-sixths are less than two-fifths.
Although it is usually overused, determining common denominators is a helpful
approach for some pairs of fractions. Learners, who make an analysis of the problem, give
and use a suitable and well-organized strategy for contrasting portions are likely to have a
better knowledge of fractions. Learners, who determine common denominators when other
effective strategies are sensible, may not understand fractions (Ebby et al., 2013).
Determining a common denominator is vital during additions and subtraction of a number of
pairs of fractions.
