Question

1. Arrange the following in ascending order :
$\frac{ - 3}{4} \: \: \frac{ - 5}{ - 12} \: \: \: \: \frac{ - 7}{16}$
​

Answer 1

Step-by-step explanation:

the lcm of 4 , 12 and 16 is 48

$\frac{ - 3}{4} = \frac{ - 3 \times 12}{4 \times 12} = \frac{ - 36}{48 } \\ \frac{ - 5}{12} = \frac{ - 5 \times 4}{12 \times 4} = \frac{ - 20}{48} \\ \frac{ - 7}{16} = \frac{ - 7 \times 3}{16 \times 3 =} = \frac{ - 21}{48} \\ ascending \: order \: will \: be \\ \frac{ - 36}{48} \: \frac{ - 21}{48} \: \frac{ - 20}{48} \\ = \frac{ - 3}{4} \: \frac{ - 7}{16} \: \frac{ - 5}{12}$
