Answer 1

Răspuns:

0,7=$\frac{7}{10}$⇒$\frac{7}{10} *10=\frac{70}{10} =7$

$0,7=\frac{7}{10}$⇒$\frac{7}{10} *100=\frac{700}{10} =70$

$\frac{7}{10} *1000=\frac{7000}{10} =700$

b).  $18,39=\frac{1839}{100}$

$\frac{1839}{100} *10=\frac{18390}{100} =183,9$

$18,39*100=1839\\18,39*1000=18390$

$9,356*10=93,56\\9,356*100=935,6\\9,356*1000=9356$

d). $0,08*10=0,8$

$0,08*100=8\\0,08*1000=80$

e).$0,0015*10=0,015$

$0,0015*100=0,15\\0,0015*1000=15$
