A RATIONAL NUMBER is any number that can be written as a fraction where the denominator cannot equal zero. In George’s terms, that means if a number is an integer, has a repeating decimal or terminating decimal, it is rational.

or t a r e num

denominator

Numbers are relatively prime if they have no common factors other than 1. The goal of simplifying fractions is to make the numerator and denominator relatively prime

GCF means Greatest Common Factor!!!!

= .333333333333 it goes on forever and ever and ever and ever and ever and ever and ever and ever and ever………………. And ever.

It’s written as .3



To write a finite decimal as a fraction, identify the place value of the digit farthest to the right (last digit). Then write all the digits after the decimal as the numerator with the place value as the denominator.

0.345 8 3458 is the numerator

The 8 is in the tenthousandths place so the denominator is 10,000

To write a fraction as a decimal, divide the denominator into the numerator. 1÷6=
