Question

Se considera fractiile ordinare x=1 7/8 și y=6/5 calculați a)x×y b)x÷y

Answer 1

$x = 1 \frac{7}{8} = \frac{7}{8}$
$y = \frac{6}{5}$

a).
$x \times y$

$\frac{7}{8} \times \frac{6}{5} = \frac{42}{40} = \frac{21}{20}$


b).
$x \div y$

$\frac{7}{8} \div \frac{6}{5} = \frac{7}{8} \times \frac{5}{6} = \frac{35}{48}$
