Ma puteti ajuta cu ex 4,5,6 va rog

Answer 1

Răspuns:

4.a)  $\frac{132}{10} = \frac{66}{5}$    b) $\frac{249}{100}$  c) $\frac{175}{100}$= $\frac{35}{20} = \frac{7}{4}$   d) $\frac{11003}{1000}$  e) $\frac{3004}{1000} =\frac{751}{250}$

5) a) $5\frac{5}{9} =$$\frac{5*9+5}{9}$= $\frac{50}{9}$   b) 7,(4) = $7\frac{4}{9}$= $\frac{7*9+4}{9}$= $\frac{67}{9}$

0,(23)= $\frac{23}{99}$       0,(40)= $\frac{40}{99}$

6. 3.2(4)=3$\frac{24-2}{90}$= $3\frac{22}{90}$= $\frac{292}{90} = \frac{146}{45}$    5.3(5)= 5$\frac{35-3}{90}$= 5$\frac{32}{90}$= $= \frac{5*90+32}{90}= \frac{482}{90}$

2,3(8)= 2$\frac{28-2}{90}$= $2\frac{26}{90}$= $\frac{2*90+26}{90}$= $\frac{206}{90}$   4, 9(05)= 4$\frac{905-9}{990}$= 4$\frac{896}{990}$ = $\frac{4*990+896}{990}$= $\frac{4856}{990}$

3,0(24)= 3$\frac{24}{990}$ = $\frac{3*990+24}{990}$= $\frac{2994}{990}$    1,2(16)= 1$\frac{216-2}{990} = 1 \frac{214}{990}$= $\frac{1*990+214}{990}$=$\frac{1204}{990}$
