Penjelasan dengan langkah - langkah:
[tex]2 \frac{2}{5 } \div (72\% \times \frac{4}{9} )[/tex]
[tex] = \frac{12}{5} \div ( \frac{72}{100} \times \frac{4}{9} )[/tex]
[tex] = \frac{12}{5} \div \frac{8}{25} [/tex]
[tex] = \frac{12}{5} \times \frac{25}{8} [/tex]
[tex] = \frac{15}{2} [/tex]
[tex] = 7 \frac{1}{2} [/tex]
Opsi C
[tex]\tt 2\frac{2}{5}\div(72\%\times \frac{4}{9})\\ \\= \frac{12}{5}\div(\frac{72}{100}\times \frac{4}{9})\\ \\= \frac{12}{5}\div(\frac{36}{50}\times \frac{4}{9})\\ \\= \frac{12}{5} \div (\frac{18}{25}\times \frac{4}{9})\\ \\=\frac{12}{5}\div \frac{72}{225} \\\\= \frac{12}{5} \div \frac{24}{75} \\\\= \frac{12}{5} \div \frac{8}{25} \\\\= \frac{300}{40}\\ \\= \frac{15}{2} \\\\= 7\frac{1}{2}~(C)[/tex]
