Rational Number review

Today was a review of working with rational numbers (fractions).  Remember rational numbers can be written in the form m/n where m & n are integers and n cannon equal 0.

To get used to working with fractions again, we were finding common denominators so we could put fractions in order from smallest to largest.

HINT - do a factor tree for the denominators to find the LCM

HOMEWORK:

Put the following rational numbers in order from smallest to largest

1.  11/8   -3/2    -16/10    -7/4
2. -3/8   -1/3   -1/4   -2/9   -7/-18
3. -3/15   -16/40   14/30   -13/20

*another hint - see if you can reduce fractions before you find the common denominator
