“My Puppy Makes a Pizza”
My puppy makes pizza.He bakes every dayIn a chef hat and apronhe's quite the gourmet.
He'll roll out some doughand he'll give it a toss,then spread on a generoustopping of sauce.
He'll heap it with cheesesand mountains of meat,but, still, it's not somethingyou'd probably eat.
For though he makes pizzawith obvious flair,it all ends up coveredwith slobber and with hair.

Greatest Common Factor
Do you remember the GCF?
18: 1, 2, 3, 6, 9, 1827: 1, 3, 9, 27
The GCF, or greatest common factor of 18 and 27 is 9.

Oh… well, let’s learn about the L C D now!
LCD stands for…
Least Common Denominator

Now, which one was the denominator?
The number on the bottom!
Now we must blend our knowledge…
How can we link the term “least common multiple” with the
term “Least Common Denominator”?Hmmm…When we listed the multiples of two or
numbers that we were comparing, the least common multiple was the smallest number
found in both or all the lists!
So, I bet the LCD works like that with fractions!
The LCD of 2/5 and 1/8 is 40.
Let’s find the LCD!Guided Practice

Multiples of the denominator: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
Multiples of the denominator: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80
So, what is the LCD or Least Common Denominator (use LCD when referring to fractions)?

Kayla practiced her violin 2 2/3 hours on Monday, 3 1/6 hours on Tuesday, and 2 3/4 hours on Wednesday. On which day did she practice the longest?
Step 1: Identify the numbers as mixed numbers with different denominators.

Step 4: Rename each fraction as an equivalent fraction with the
LCD as the denominator (12). Monday8 x 4 = 323 4 12

So, now that you have equivalent fractions with matching denominators, which day did Kayla
practice the longest?
