What's a Rational Number?

A rational number can be represented as a fraction of two integers, a over b, with b≠0
5, -1 and 2/5, 0.25, and 0.666 repeating are all rational numbers
5 is the same as 5 over 1
-1 and 2/5 is the same as -7/5
0.25 is the same as 1/4
0.666 repeating is the same as 2/3
Notice that our fractions have integers as the numerator and the denominator, and also that the denominator is not 0

1. A rational number can be written as a fraction
2. An integer is a whole number that can be positive, negative, or 0
1. A rational number can be written as a fraction of two integers, a over b, with b ≠ 0
2. An integer is a whole number that can be positive, negative, or 0
1. 5, -1 and 2/5, 0.25, and 0.666 repeating are rational numbers
2. These are all rational numbers because they can be represented as a fraction of two integers, and without dividing by 0
1. 5, -1 and 2/5, 0.25, and 0.666 repeating are rational numbers
1. 5, -1 and 2/5, 0.25, and 0.666 repeating are rational numbers
2. 5 is the same as 5 over 1
3. Both 5 and 1 are integers, and the denominator does not equal 0
4. -1 and 2/5 is the same as -7 over 5
5. Again, both -7 and 5 are integers, and the denominator does not equal 0
6. 0.25 is the same as 1/4
7. 0.666 repeating is the same as 2/3
