Answer 1

Answer:

by multiplying the numerator and denominator by -6 and the result is 24 by -30

Answer 2

Answer:

$- \frac{16}{20}$

Step-by-step explanation:

$\frac{ - 4}{5} \times \frac{?}{?} = \frac{?}{ - 20}$

now find how do we get 20 directly.

$\frac{ - 4}{5} \times \frac{4}{4} = \frac{ - 16}{20} \frac{( - \times + - )}{ + \times + = + }$

even though its 16 by 20 by standard it mentioned as

$- \frac{16}{20}$

thereby your answer is

16 by 20
