boleh bantu ? sorry dotony gerak

d)
6 = 2 × 3
4 = 2²
KPK = 2² × 3 = 4 × 3 = 12
[tex]2 \frac{1}{6}- \frac{3}{4} =[/tex]
[tex]2 \frac{2}{12}- \frac{9}{12} =1 \frac{12+2}{12} - \frac{9}{12} =1 \frac{14}{12} - \frac{9}{12} =1 \frac{5}{12} [/tex]

e)
5 = 5
6 = 2 × 3
KPK = 2 × 3 × 5 = 30
[tex]3 \frac{3}{5} -1 \frac{5}{6} =\\ 3 \frac{18}{30} -1 \frac{25}{30} =2 \frac{30+18}{30} -1 \frac{25}{30}=2 \frac{48}{30} -1 \frac{25}{30}=1 \frac{23}{30} [/tex]
