Multiple Choice

What is the Least Common Multiple (LCM) of 2 and 4?

• 2

• 4

• 8

Multiple Choice

Step #1: Are the denominators the same?

• yes

• no

Multiple Choice

Step #2: Can I turn one into an equivalent fraction that has the same denominator?

• yes

• no

Multiple Choice

Step #3: What is the least common multiple of the denominator of both fractions (3 and 6)?

• 3

• 6

• 9

• 12

Multiple Choice

Step #4: Generate an equivalent fraction to 2/3 with six as the denominator?

• 2/6

• 3/6

• 4/6

• 3/12

Multiple Choice

Step #5: Finally compare the two fractions. Which fraction is greater, 2/3 OR 5/6?

• 2/3

• 5/6

Multiple Choice

The first thing we will do before ordering these fractions, we will find the Least Common Multiple (LCM) of all 3 denominators (4, 6 and 12). Select the LCM below:

• 4

• 6

• 12

• 16

Multiple Choice

Now that we have found the Least Common Multiple (LCM) of all 3 denominators (4, 6, and 12). Let's solve for the numerators:

3 x 3 =

• 4

• 6

• 9

• 12

Multiple Choice

Now that we have found the Least Common Multiple (LCM) of all 3 denominators (4, 6, and 12). Let's solve for the numerators:

5 x 2 =

• 5

• 10

• 15

• 20

Multiple Choice

Now that we have found the Least Common Multiple (LCM) of all 3 denominators (4, 6, and 12). Let's solve for the numerators:

3 x 4 =

• 6

• 4

• 8

• 12

Multiple Choice

Finally, we can use or new equivalent fractions with the same denominators, to help us to order the fractions, (3/4, 5/6, and 2/3) in order from least to greatest.

• 6/6, 9/12, 2/8

• 5/6, 3/4, 2/3

• 2/3, 5/6, 3/4

• 2/3, 3/4, 5/6
