[tex] = \frac{1}{12} \div \frac{1}{4} + \frac{1}{5} \times \frac{1}{15} \\ \\ = \frac{1}{12} \times 4 + (\frac{1}{5 \times 15} ) \\ \\ = \frac{4}{12} + \frac{1}{75} \\ \\ = \frac{1}{3} + \frac{1}{75} \\ \\ = \frac{25 + 1}{75} \\ \\ = \frac{26}{75} [/tex]

Pembahasan:

1/12 : 1/4 + 1/5 × 1/15
= 1/12 × 4/1 + 1/5 × 1/15
= 4/12 + 1/75
= 1/3 + 1/75
= 25/75 + 1/75
= 26/75 → Opsi A
