Question

in ascending order -2/-5,-3/7,-1/-9,7/10​

Answer 1

Answer:

$lcm \: of \: 5 \: \: 7 \: \: 9 \: \: 10 \: = 630$

$- \frac{2}{5} = - \frac{2 \times 126}{5 \times 126} = - \frac{252}{630}$

$- \frac{3}{7} = - \frac{3 \times 90}{7 \times 90} = - \frac{270}{630}$

$- \frac{1}{9} = - \frac{1 \times 70}{9 \times 70} = - \frac{70}{630}$

$\frac{7}{10} = \frac{7 \times 63}{10 \times 63} = \frac{441}{630}$

The required ascending order is,

$- \frac{3}{7} \: \: \: - \frac{2}{5} \: \: \: - \frac{1}{9} \: \: \: \: \: \frac{7}{10}$
