WRITE THE OBJECTIVE IN YOUR OWN WORDS IN YOUR MATH JOURNAL:

SWBAT write fractions and mixed numbers in simplest form.

Lesson 1.1

Explore! Fraction Tiles

Each large rectangle below represents one whole. Each rectangle is divided into equal parts. It is called a fraction bar.

Step 1 Write a fraction to representnumber of shaded sectionstotal number of sections

for each fraction bar.

Step 2 Match each fraction in the left column with its equivalent fraction in the right column. Write the pair of equivalent fractions.

For example, .1 2

5 10

Step 3 Write a third equivalent fraction for each pair in Step 2.

Explore! Fraction Tiles

Step 5 The fractions in the left column are in simplest form. Look at the fractions in the left column compared to those in the right column and explain what simplest form means.

Step 4 Draw two fraction bars to show and . Are these equivalent fractions? Explain. If so, write a third equivalent fraction to and .

WRITING FRACTIONS IN SIMPLEST FORMDivide the numerator and denominator by the greatest common factor (GCF).

- OR -

Divide the numerator and denominator by common factors until the only common factor is 1.

EXAMPLE 3a. Write the fraction in simplest form:

Find GCF of 20 and 50. 20 = 2 2 5 50 = 2 5 5

The common prime factors GCF = 2 5 = 10of 20 and 50 are 2 and 5.

Divide the numerator anddenominator by the GCF.

b. Write the fraction in simplest form:

One common factor of 45 and 60 is 5.

Divide the numerator anddenominator by 5.

A common factor of 9 and 12 is 3.

Divide the numerator anddenominator by 3.
