as a rational number with denominator
5
(b) -20
(C) 35
(a) -15​

Answer 1

Answer:

-3 as a rational number with denominator 5 is -15/5 i.e. a)-15

Answer 2

Step-by-step explanation:

$a)denominator \: = - 15$

$l.c.m = - 15$

$\frac{3}{5} = \frac{3 \times - 3}{5 \times - 3} = - \frac{9}{15}$

$b) \: denomiator \: = - 20$

$l.c.m \: = - 20$

$\frac{3}{5} = \frac{3 \times - 4}{5 \times - 4} = - \frac{12}{20}$

$c) \: denominator \: = 35$

$l.c.m \: = 35$

$\frac{3}{5} = \frac{3 \times 7}{5 \times 7} = \frac{21}{35}$
