ποΈ What are Rational Numbers?
- Rational numbers can be written as a fraction of two integers.
- They include fractions, terminating decimals, integers, and recurring decimals.
ποΈ What are Irrational Numbers?
- Irrational numbers are decimals that never end and do not repeat.
- They cannot be written as a fraction.
ποΈ How to Locate Fractions on a Number Line?
- Rewrite the fraction as a mixed number, for example .
- Go to 3 on the number line, split the gap from 3 to 4 into 3 equal parts, and move 2 parts to find 11/3.
ποΈ How to Locate Decimals on a Number Line?
- Rewrite the decimal to separate the whole and decimal parts, for example .
- Go to β2, divide the gap from β2 to β3 into 10 equal parts, and move 7 parts to find β2.7.
