2 1/5 ÷ ( 1,6÷2/3)-2/5 tolong dijawab pake caranya diubah kebentuk persen atau pecahan,jangan asal asalan

2 1/5= 2,20 = 220 %
1,6 = 160 %
2/3 = 33 %
2/5 = 40%

220 : (160 :33) - 40 = 220 : 4,84 - 40= 45,45 - 40 = 5,45 %

Angkanya sulit :D
Maaf kalo salah
Semoga membantu :)

[tex]2 \frac{1}{5} \div (1.6 \div \frac{2}{3} ) - \frac{2}{5} \\ = \frac{11}{5} \div ( \frac{16}{10} \times \frac{3}{2}) - \frac{2}{5} \\ = \frac{11}{5} \div \frac{12}{5} - \frac{2}{5} \\ = ( \frac{11}{5} \times \frac{5}{12} ) - \frac{2}{5} \\ = \frac{11}{12} - \frac{2}{5} \\ = \frac{55}{60} - \frac{24}{60} \\ = \frac{31}{60} [/tex]


31/60 × 100%
= 31/3 × 5%
= 155/3%
= 51 2/3%
= 51,67%
