A
rational number is a number which can be expressed as a fraction whose
numerator and denominator are both integers and whose denominator is not equal
to zero. Rational numbers include all integers, fractions, mixed numbers, and
some decimal numbers.
Note : All terminating and repeating decimal
numbers are rational numbers because those numbers can be expressed as a
fraction. On the other hand, a non repeating number and non terminating
decimal, like square root of 2, is an irrational number.
\(Convert \ -3.48 \ into \ a \ fraction\)
\(-3.48 = \dfrac{-3.48}{1}\) \(Convert \ to \ fraction\)
Multiply by 1 to eliminate two decimal places.
\(Numerator = -3.48 * 10 * 10 = -348
Denominator = 1 *10 * 10 = 100\)
\(Our \ new \ fraction \ is \ \dfrac{-348}{100}\)
\(The \ value \ is \ 0.034800000000000005\)
\(= Given \ value \ is \ Rational.\)
