Question

Calculeaza 1si 7supra18

Answer 1

1 si 7/18 = 25/18 = 1,3(8)

Answer 2

$1\dfrac{7}{18} = 1+\dfrac{7}{18} = ^{\big{18)}}1+\dfrac{7}{18} = \dfrac{1\cdot 18}{18}+ \dfrac{7}{18} =\dfrac{1\cdot18+7}{18} = \dfrac{18+7}{18} = \dfrac{25}{18} \\ \\ \\ 1\dfrac{7}{18} =\underset{...............................................................}{ }=\dfrac{1\cdot18+7}{18} = \dfrac{18+7}{18} = \dfrac{25}{18}$

Calculul de deasupra punctelor, este calculul din spatele acestui concept, de 1 intreg si ceva.

Asta inseamna practic 1 intreg si ceva, inseamna 1 + acea fractie. Daca uiti metoda, doar scrii 1+ fractia, o aduci la acelasi numitor si iti amintesti imediat de ea. :)
