Question

cate intregi se pot forma din:2 doimi,10 doimi,15 treimi,28 patrimi,100 zecimi?

Answer 1

$2\ doimi = \ \frac{2}{2} \\ \frac{2}{2}=\boxed{1 \ intreg} \\ 10 \ doimi \ = \ \frac{10}{2} \\ \frac{10}{2} = \boxed{5 \ intregi} \\ 15 \ treimi \ = \frac{15}{3} \\ \frac{15}{3} = \boxed{5 \ intregi} \\ 28 \ patrimi = \ \frac{28}{4} \\ \frac{28}{4}= \ \boxed{7 \ intregi} \\ 100 \ zecimi = \frac{100}{10} \\ \frac{100}{10}= \boxed{10 \ intregi}$
