Question

which of the two rational number is greater in each of the following pairs? 11 by -18 or -5 by 18​

Answer 1

Step-by-step explanation:

The LCM of the denominators 5 and 8 id 40

$therefour \\ \: \frac{4}{ - 5} = \frac{4 \times 8}{ - 5 \times 8} = \frac{32}{ - 40} = \frac{ - 32}{40}$

$and \\ = \frac{ - 7}{8} = \frac{ - 7 \times 5}{8 \times 5} = \frac{ - 35}{40}$

$now \: \\ - 32 > - 35$

$= \frac{ - 32}{40} > \: \frac{ - 35}{40}$

$hence \\ \frac{4}{ - 5} \: > \: \frac{ - 7}{8}$

$therefour \\ \frac{4}{ - 5} greater$
