(1) 1/5 + ... = 1/15 (2). FPB 12 dan 32 (3). KPK 12 dan 46 Tolong ya di jawab teman teman...

1)
[tex] \frac{1}{5}+...= \frac{1}{15} \\ ...= \frac{1}{15}- \frac{1}{5} \\ ...= \frac{1}{15}- \frac{3}{15} \\ ...=- \frac{2}{15} [/tex]
Maka, [tex] \frac{1}{5}+(- \frac{2}{15})= \frac{1}{15} [/tex]

2) 12 = 2² × 3
32 = 2⁵
FPB = 2² = 4

3) 12 = 2² × 3
46 = 2 × 23
KPK = 2² × 3 × 23 = 276
