Question

Comparati cu semnele < = > a)11/7+11/4 si 11/7×11/4; b)11/8+11/3 si 11/3×11/8; c)5/2+5/3 si 5/2×5/3;

Answer 1

$a) \frac{11}{7}+ \frac{11}{4} =\frac{11}{7}* \frac{11}{4}$
Deoarece:
$\frac{11}{7} + \frac{11}{4}= \frac{121}{28} \\ \frac{11}{7} * \frac{11}{4}= \frac{121}{28}$
[tex] b) \frac{11}{8}+ \frac{11}{3}= \frac{11}{3}*\frac{11}{8} \\ c) \frac{5}{2} +\frac{5}{3} = \frac{5}{2} * \frac{5}{3} [/tex]
