Any number that has 9 as a factor must also have what other number as a factor?
Any number that has 9 as a factor, must also have 3 as a factor because 3 is a factor of 9 and 9 is a multiple of 3.

EQUIVALENT FRACTIONS are fractions that have the same value but different denominators. Name a fraction that is equivalent to 1/2.
We can say that 2/4 and 4/8 are EQUIVALENT to 1/2 because the total value is the same but the size of the pieces are different.

List two numbers that are multiples of both 2 and 5.
10 and 20 are both multiples of 2 and 5 because you can can to 10 and 20 by skip counting by 2 or 5 (in other words, they are both factors of 10 and 20)

Subtract: 4 and 2/12 - 2 and 4/12
1 and 10/12 or 1 and 5/6

Name a fraction that is EQUAL to 2/3. *Hint: This is a trick question*
2/3 is the only answer to this question. We say that 2/3 is EQUAL to 2/3 because the numerator and the denominator are *EXACTLY* the same. We would NOT say that 2/3 is EQUAL to 4/6, we could call them EQUIVALENT.

If we have a number line that goes only from 0 to 1, can we put 12/6 on that number line?
No, you cannot put 12/6 on a number line that only goes up to 1 whole because 12/6 is larger than 1 whole.

4/6 = ?/24 Draw it and prove it!
4/6 = 16/24 (proved by drawing a multiplication arrow of x2 to the new num. and denom.)

True or False, the FIRST common multiple of 6 and 12 is 72.
False, the first common multiple of 6 and 12 is 12. 1x6=6 1x12=12 2x6=12 2x12=12

********DAILY DOUBLE*********** Add the following and then convert it to an improper fraction: 1 and 8/9 + 2 and 4/6 **Hint: In order to add or subtract fractions, the denominators must be the same.
First you must change the fractions so that the denominators are the same, so find the Least Common Multiple of 9 and 6 (18). 8/9 = 16/18 AND 4/6 = 12/18 1 and 16/18 + 2 and 12/18 = 3 and 28/18 Simplify: 28/18 both are divisible by 2 so 14/9, so we have 3 and 14/9 Convert to improper fraction: 41/9

I have a seesaw with two fractions on each side. On one side is the fraction 3/9---on the other side is 15/45. Explain what will happen to this seesaw and prove it with a drawing.
The seesaw will balance because 3x5 = 15 (new numerator) and 9x5=45 (new denominator).
