Answer 1

Step-by-step explanation:

(4)

the rational number between

$\frac{ - 5}{6} and \frac{5}{8} is \: average \: of \: \frac{ - 5}{6} and \frac{5}{8}$

$\frac{1}{2} ( \frac{ - 5}{6} + \frac{5}{8} ) = \frac{1}{2} ( \frac{ - 20 + 15}{24} ) = \frac{1}{2} ( \frac{ - 5}{24} ) = \frac{ - 5}{24}$

the second rational number is calculated by calculating the average of

$\frac{ - 5}{6} and \frac{ - 5}{24}$

$\frac{1}{2} ( \frac{ - 5}{6} + \frac{ - 5}{24} ) = \frac{1}{2} ( \frac{ - 20 - 5}{24} ) = \frac{1}{2} \times \frac{ - 25}{24} = \frac{ - 25}{48}$

(5)

a. -21/60+35/60

-21+35/60

14/60=7/30

b.9/16*4/12+9/16*-3/9

3/16+(-3)/16

3-3/16
