1/25 : 12℅ : 0,25 × 3 1/2

1/25 ÷ 12 %
= 1/25 ÷ 12/100
= 1/25 × 100/12 = 4/12
= 4/12 ÷ 0,25
= 4/12 ÷ 25/100
= 4/12 × 100/25 = 100/75
= 100/75 × 3 1/2
= 100/75 × 7/2 = 350/75
= 4 2/3

maaf kalo salah

[tex] \frac{1}{25} \div 12\% \div 0.25 \times 3 \frac{1}{2} \\ = \frac{1}{25} \div \frac{12}{100} \div \frac{25}{100 } \times \frac{7}{2} \\ = \frac{1}{25} \times \frac{100}{12} \times \frac{100}{25} \times \frac{7}{2} \\ = \frac{14}{3} [/tex]
