Question

Cum$\frac{1}{7}$ sa transform o fractie precum " 4 $\frac{1}{7}$ in $\frac{x}{y}$
Si nr. 2.72 in fractie $\frac{x}{y}$
Va rog ajutatima

Answer 1

$a \frac{x}{y}= \frac{ay+x}{y}$

$4 \frac{1}{7}= \frac{4\cdot7+1}{7}= \frac{29}{7}$




$2.72= \frac{272}{100}$

$\overline{a_1a_2...a_n,b_1b_2...b_p}= \frac{\overline{a_1a_2...a_nb_1b_2...b_p}}{10^p}$
