Question

Calculati valoarea raportului de numar:
a)2,1(3) si $\frac{4}{3}$

Answer 1

$2,1(3)=2\dfrac{13-1}{90}=2\dfrac{\ 12^{(6}}{90}=2\dfrac{2}{15}=\dfrac{32}{15}$

Deci, avem:

[tex]a=\dfrac{32}{15}, \ \ \ b = \dfrac{4}{3} \\\;\\ \dfrac{a}{b}=\dfrac{\dfrac{32}{15}}{\dfrac{4}{3}} =\dfrac{32}{15} : \dfrac{4}{3} = \dfrac{32}{15} \cdot \dfrac{3}{4} =\dfrac{16}{10}=1,6 [/tex]
