Explore numbers that can be written as a fraction of two integers, and learn to compare and order them.
A rational number is any number that can be written as p/q, where p and q are integers and q is not zero. This includes whole numbers, fractions, and their negatives.
Is −3/4 a rational number?
Yes, since −3 and 4 are both integers
Write 5 as a rational number in p/q form.
5/1
To compare rational numbers, convert them to a common denominator, then compare the numerators directly.
Which is greater: −1/2 or −1/4?
−1/4, because it's closer to zero
Compare 2/3 and 3/5 using a common denominator.
2/3 = 10/15, 3/5 = 9/15, so 2/3 is greater
1. Is 7 a rational number? Explain.
2. Which is greater: −2/3 or −5/6?
3. Compare 3/4 and 5/8 using a common denominator.
4. Write −0.5 as a rational number in p/q form.
5. Arrange in ascending order: 1/2, −1/2, 1/4
