400
Are these fractions put in the right order, from LEAST TO GREATEST: 2 1 5 ? __ , __ , __ 3 4 6
What is no? The order should be: 1 2 5 . __ , __ , __ 4 3 6
500
We use THIS to find the least common denominator of three fractions with unlike denominators.
What is multiples?
500
Can 1 be prime or composite? Why or why not?
No, because 1 has only 1 factor: itself. We say prime factors have only 2 factors: 1 and itself. However, 1 is itself and therefore, cannot be prime. 1 cannot be composite because it does not have more than 2 factors.
500
Make an equivalent fraction to 2 and explain how you got it. __ 6
1/3, 3/9, 4/12, 5/15, ...
500
Is the correct symbol used to compare these two fractions: 3 5 ? __ > __ 6 9
What is no? By using cross-multiplication, we know that 9 x 3 = 27 and 6 x 5 = 30. 27 < 30. Therefore, the symbol should be < (less than).

Explain the steps to ordering fractions using cross multiplication.
First, compare each fraction to the other fractions by using cross-multiplication (ie. Is the first fraction smaller or bigger than the second fraction, is the second fraction smaller or bigger than the last fraction, and is the first fraction smaller or bigger than the last fraction?). Next, circle the bigger fraction in each of the comparisons (circle the ones that "won"). Last, look at which fraction was not circled at all (least), which fraction was circled once (middle), and which fraction was circled twice (greatest). Then, put them in order from least to greatest.
