GUIDE CARD
Study this.Do you want to have some fun?
Before you start the game in renaming decimals as fractions, study the examples below.
0.8 = 810 0.25 = 25100
8.82 = 8 82100
Think…Think…Think…Let us have a short review:How do we rename a decimal as a fraction?
To rename 0.5 and 0.25 as fractions, we can use regions.
0.25= 25100
0.5 or 510 12
0.5 = 510 or 12

GUIDE CARDHere is another way to rename a decimal as a fraction.
Rename 0.8 as a fraction with denominator of 10
0.8 = 810
Find the “Greatest Common Factor” (GCF) of the numerator and denominator
How do we find the greatest common factor of 2 numbers? First we find the prime factorization of both numbers using the factor tree8 10
4 x 2 5 x 2
2 x 2Divide the numerator and denominator by the GCF
810 = 8÷210÷2=45
So, 0.8 = 45
4
Write the decimal as a fraction with a denominator of 10 or 100. Then divide the numerator and denominator by their greatest common factor (GCF) to change the fraction to lowest terms.

Activity 1Practice What You Learned
Write each decimal in fraction form.Ex: 0.3= 3
10 0.26 = 26100 5.2=5 210

To rename a decimal as a fraction in lowest terms, write it first as a fraction with a denominator of 10 or 100. Then divide the numerator and denominator by their greatest common factor (GCF) to change the fraction to lowest terms.
JOB WELL DONE!
Let’s try some more!
Write each decimal as a fraction in lowest terms. Ex. 0.12= 12100
12÷4100÷ 4
= 325 so, 12100 = 325
1. 0.962. 0.123. 1.804. 2.255. 0.266. 2.357. 0.448. 3.679. 8.8210. 7.55
