The type of numbers, rational and irrational from the numbers Keisha writes are;
a. Rational numbers; -9, 3.0, 2, and 2.42
b. Irrational numbers; √8
<h3>What is the difference between rational and irrational numbers?</h3>Rational numbers are numbers are numbers that can be expressed as a ratio of two whole numbers P/Q, in which, <em>Q </em>≠ 0
Irrational numbers are those that cannot be expressed as a fraction P/Q
The given numbers are;
-9, √8, 3.0, 2, 2.42
- -9 = -9/1
- √8 = 2•√2 (√2 cannot be expressed as a fraction of two whole numbers)
- 3.0 = 3/1
- 2 = 2/1
a. The rational numbers are therefore;
- -9, 3.0, 2, and 2.42
b. The irrational number is; √8
