Question

x+3/5 si 19/25 sunt echivalente , atunci x=...

Answer 1

$x+ \frac{3}{5}= \frac{19}{25} \Rightarrow x= \frac{19}{25}- \frac{3}{5}= \frac{19}{25}- \frac{15}{25}= \frac{4}{25}. \\ \\ \underline{Solutie}: ~x= \frac{4}{25}. \\ \\ numere~"echivalente"=numere~egale$

Answer 2

x+3/5=19/25
x+0,6=0,76
x=0,76-0,6
x=0,16
