Mapel. : Matematika
Bab. : Operasi Pecahan
Sub Bab : Pecahan

Pembahasan:

7/15 × 0,7 : 14/20 + 0,8 - 5/12
= 7/15 × 7/10 : 14/20 + 8/10 - 5/12
= 49/150 : 7/10 + 4/5 - 5/12
= 49/150 × 10/7 + 4/5 - 5/12
= 490/1050 + 4/5 - 5/12
= 70/150 + 4/5 - 5/12
= 7/15 + 4/5 - 5/12
= 28/60 + 48/60 - 25/60
= 76/60 - 25/60
= 51/60 → Jwbnya

[tex] \frac{7}{15} \times 0.7 \div \frac{14}{20} + 0.8 - \frac{5}{12} \\ = \frac{7}{15} \times \frac{7}{10} \times \frac{20}{14 + \frac{8}{10} } - \frac{5}{12 } \\ = \frac{7}{15} \times \frac{2}{2} + \frac{8}{10} - \frac{5}{12} \\ = \frac{7}{15} \times 1 + \frac{8}{10} - \frac{5}{12} \\ \frac{7}{15} + \frac{8}{10} - \frac{5}{12} \\ = \frac{28 + 48 - 25}{60} = \frac{51}{60} \\ \\ \\ [/tex]
