Estimate: 15 -16, 17 -18
19, 20, 24, 26, 27 Sec. 6.1 Rational Number Ideas

We commonly refer to situations like :
1/4 of a pizza...
3/4 of Americans surveyed...
15% of college students...

These are examples of rational numbers , which are
simply quotients a / b of two integers , where b ≠ 0.

When you think of rational numbers , you should
think of a part & a whole.

Shade the given fraction of the whole . The fraction is shown . What is the whole? Equivalent fractions  Example:
1. Use the Fundamental Law of Fractions (if
possible) to change each rational number into
decimal form . 2. Estimate the location of each of the fractions
above on the number line .

Fractions and Decimals
a) The number 12.76 is a rational number... why? b) Write 12.76 in expanded notation . Express in decimal form : Claim: Every rational number can be expressed
as a terminating or repeating decimal.
