D. Rational numbers.
Rational numbers are the numbers that can be expressed as a fraction where both the numerator and the denominator are integers, and the denominator is not zero. Since −1.7 can be written as the fraction −17/10, where both −17 and 10 are integers and 10 is not zero, −1.7 is a rational number. Rational numbers can include integers, fractions, and terminating or repeating decimals.
