Answer 2

Answer:

$\frac{9}{20} > \frac{ - 7}{24}$

Step-by-step explanation:

$\frac{ - 7}{24} \: \: \: \: \frac{9}{20} \\ \\ multiply \: and \: divide \: numerator \: by \: 20 \: for \: first \: fraction \: and \: by \: 24 \: forsecond \: \\ fraction$

$\\ \\ \frac{ - 7 \times 20}{\ 24 \times 20} \: \: and \: \: \: \frac{9 \times 24}{20 \times 24}$

$\frac{ - 140}{480} \: \: \: and \: \: \: \frac{216}{480}$

$\\ therefore \: \: \: \: \frac{ - 140}{480} < \frac{216}{480 } \\ \\ or \: \: \frac{ - 7}{24} < \frac{9}{20}$
