Jawab:
1/4
Penjelasan dengan langkah-langkah:
1. Diketahui:
Suku pertama (a₁) = 1/4
Jumlah deret tak hingga (S) = 1/3
2. Ditanya:
Rasio (r)
3. Jawab:
[tex]= > S = \frac{a}{1-r}[/tex]
[tex]= > \frac{1}{3} = \frac{1/4}{1-r}[/tex]
[tex]= > 1-r = \frac{1/4}{1/3} = \frac{1}{4} * \frac{3}{1} =\frac{3}{4}[/tex]
[tex]= > r = 1-\frac{3}{4} = \frac{4}{4} - \frac{3}{4}[/tex]
[tex]= > \frac{1}{4}[/tex]
