15 per 25 dikali 1 per 6 dikurangi 3 per 75

15/25 di kali 1/6 -3/75
=9/150 dikali 25 /150 -6/150
=34/150-6/150=28/150

(semoga membantu)

[tex] \frac{15}{25} \times \frac{1}{6 } - \frac{3}{75} = \frac{15}{150} - \frac{3}{75} = \frac{30}{75} - \frac{3}{75} = \frac{27}{75} \div 3 = \frac{7}{25} [/tex]
