Răspuns:

a. intregi: -17, -371, -46

b. naturale: 0, 173, 18,

c. rationale: 9,3, $\frac{19}{5}$, 0,4 , 5.01, 12,9, 7$\frac{5}{11}$, $\frac{1}{99}$

d. rationale negative: -8,(1) , -3$\frac{9}{14}$ , -7,1(2)

Explicație pas cu pas:

9,3 = $\frac{93}{10}$

0,4 = $\frac{4}{10}$ = $\frac{2}{5}$

5.01 = $\frac{501}{100}$

12,9 = $\frac{129}{10}$

7$\frac{5}{11}$=$\frac{7*11+5}{5}$=$\frac{82}{5}$

-8,(1) = -$\frac{81-8}{9}$=-$\frac{73}{9}$

-7,1(2) = -$\frac{712-71}{90}$= -$\frac{641}{90}$

-3$\frac{9}{14}$ = - $\frac{3*14+9}{14}$ = -$\frac{31}{14}$
