Question

Fie a=0,(3) și b=3 supra 2 . Calculați a•b

Answer 1

a=0,(3)=3/9=1/3

b=3/2

1/3x3/2=

=1/2

Succes!

Answer 2

$a = 0,(3) = \frac{3}{9} ^{(3} = \frac{3 : 3}{9 : 3} = \frac{1}{3} \\ \\ b = \frac{3}{2} \\ \\ a \times b = \frac{1}{3} \times \frac{3}{2} = \frac{1 \times 3}{3 \times 2} = \frac{3}{6} ^{(3} = \frac{3 : 3}{6 : 3} = \frac{1}{2}$
