Question

Mă ajutaţi vă rog cu calculul 1supra8+1supra8×4?

Answer 1

$\dfrac{1}{8} + \dfrac{1}{8} \times 4 = \\ \\ \dfrac{1}{8} + \dfrac{1*4}{8} = \\ \\ \dfrac{1}{8} + \dfrac{4}{8} = \dfrac{5}{8}$

Answer 2

1 / 8 + 1 / 8 x 4 =

= 1 / 8 + 1 / 2

=  1 / 8 + 4 / 8 ( am amplificat a doua fractie cu 4 )

= 5 / 8
