Question

Calculati:
modul de$\frac{1}{2} - \frac{1}{3}$ - modul de $\frac{1}{4} - \frac{1}{3}$

Answer 1

1/2-1/3=3/6-2/6=1/6=1/6[in modul sau valoarea absoluta];
1/4-1/3=3/12-4/12=-1/12=1/12[in modul sau valoarea absoluta];

Answer 2

I $\frac{1}{2} - \frac{1}{3}$ I = $\frac{1}{2} - \frac{1}{3}$
I $\frac{1}{4} - \frac{1}{3}$ I = $\frac{1}{3} - \frac{1}{4}$
I $\frac{1}{2} - \frac{1}{3}$ I - I $\frac{1}{4} - \frac{1}{3}$ I = $\frac{1}{2} - \frac{1}{3}$ -  $\frac{1}{3} + \frac{1}{4}$ = $\frac{1}{2} - \frac{2}{3} + \frac{1}{4} = \frac{6-8+3}{12} = \frac{1}{12}$
