INTRODUCTION
Mathematical foundations for algebra success begin in the
early grades. The National Mathematics Advisory Panel em-
phasized the importance of understanding fraction concepts
for success in algebra and real-world problem solving. The
Panel stated that proficiency with fractions is “foundational
for algebra and, at the present time, seems to be severely un-
derdeveloped” (U.S. Department of Education, 2008, p. xvii).
Wu (2001) argued that “the proper study of fractions provides
a ramp that leads students gently from arithmetic to algebra.
But when the approach to fractions is defective, that ramp
collapses” (p. 1). Success in algebra is important because it
can help students attain the skills needed to succeed in post-
secondary education and society (Weissert, 2014). As noted
by Usiskin (1995), while people can live without algebra,
they will not appreciate what is occurring in their world and
“will not be able to participate fully in our technological soci-
ety” (p. 37). Not knowing algebra is like a person in a foreign
country and, not knowing the local language, does not know
what they are missing.
The present study extends the work of Zientek, Younes,
Nimon, Mittag, and Taylor (2013) who investigated the bias
and accuracy of prospective teachers' confidence in perform-
ing fraction operations and the extent to which fraction op-
erations predicted prospective teachers' ability to solve three
algebra equations in one variable. Using the same data set,
the current study reports on the solution pathways chosen by
respondents to solve an arithmetical equation that contains
fractions and the errors that were made along those pathways.

Abstract
We analyzed the solution pathways and errors found in the written responses of 469
prospective teachers solving an equation containing fractions. The majority (332, or
70%) used an algebraic method; 141 of the 332 (42%) were correct, and 22% of the
algebraic methods were abandoned before a solution was obtained. We identified
the steps in the written solutions, determined which solution pathways led to the
correct solution, and identified common errors in the solution pathways of respond-
ents who incorrectly solved the equation. Respondents initially attempted different
methods. The most common method was solving by using fractions, but the majority
of respondents who solved by using mixed numbers were able to correctly solve the
problem. Common errors related to fraction arithmetic and the distributive property.
Nearly all of the abandoned pathways contained no errors, but ended with a step that
likely would precede an operation with fractions. Our findings suggest that the ability
to solve an arithmetic equation with no fractions was necessary, but not sufficient,
to solve an arithmetic equation involving fractions, and that the problem of solving
equations with fractions was more closely tied to one's difficulties with rational num-
ber arithmetic and less with one's understanding of algebra.
