Question

Cum se impart 3 fractii ordinare , care fractie se inverseaza a doua sau a treia ?

Answer 1

Fractiile se inverseaza pe rand, ca in exemplul urmator:

$\frac{14}{27} \div \frac{7}{9} \div \frac{2}{ 3} =$

$= \frac{14}{27} \times \frac{9}{7} \div \frac{2}{3} =$

$= \frac{3}{2} \div \frac{2}{3} =$

$= \frac{2}{3} \times \frac{3}{2} =$

$= 1$
