Answer 1

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

What is the difference between rational and irrational numbers?

Rational numbers are numbers are numbers that can be expressed as a ratio of two whole numbers P/Q, in which, Q ≠ 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

• $2.42 = \frac{242}{100} = 2 \frac{21}{50}$

a. The rational numbers are therefore;

• -9, 3.0, 2, and 2.42

b. The irrational number is; √8
