Question

arrange the rational numbers in descending order 2/5,(-3)/(-4),1/2,(-7)/(-6),0​

Answer 1

in descending order =7/6,(-3)/(-4),1/2,2/5,0

Answer 2

$\frac{2}{5}, \: \: \frac{ - 3}{ - 4}, \: \: \frac{ 1}{2}, \: \: \frac{ - 7}{ - 6},0 \\ we \: could \: write \\ \frac{2}{5} \: \: \frac{3}{4} \: \: \frac{1}{2} \: \: \frac{7}{6} \\ step \: 1 \: same \: the \: denominator \\ \frac{2}{5} \times \frac{12}{12} = \frac{24}{60} \\ \frac{3}{4} \times \frac{15}{15} = \frac{45}{60} \\ \frac{1}{2} \times \frac{30}{30} = \frac{30}{60} \\ \frac{7}{6} \times \frac{10}{10} = \frac{70}{60} \\ step \: 2 \: desending \: order \: according \\ \: to \: numerator \\ so \: desending \: order \: is\\ \frac{-7}{-6} \: \: \: \frac{-3}{-4} \: \: \: \frac{1}{2} \: \: \: \frac{2}{5},0$
