Introduction
Set up the activity by showing the students how to
enter mixed numbers into the calculator, add and
simplify them.
1. Have students practice adding mixed numbers.
a. 4 + 3 8
b. 9 + 6 16
c. 5 + 3 8
d. 8 + 7 15
2. Have students practice simplifying fractions and
mixed numbers.

³ Hint: Before you begin, make sure that
the TI-34 MultiView calculator is in
MathPrint™, Un/d, and Mansimp
modes.
³ To simplify a fraction or a mixed
number, enter the number. There are
two options for simplying a fraction.
1. Press
}, enter a factor that is
common to both the numerator and
denominator, then press
<. This
allows students to use mental math
to simplify the fraction. Students
repeat this process until the fraction
is simplified. (No down arrow is
displayed.)
2. Press
} <. The simplified
fraction and the factor used for the
simplifcation are displayed.
Students may need to press
}
< more than once to get the
fraction to its lowest terms. Students
can write down all factors used in
the simplification to find the
greatest common factor of the
numerator and denominator.
